blotting 30秒で
- Blotting is the careful absorption of liquid using vertical pressure, common in cleaning and art.
- In molecular biology, it is a key technique for transferring DNA, RNA, or proteins to a membrane.
- It differs from wiping because it avoids friction, preventing smearing or damage to delicate surfaces.
- Commonly used tools include blotting paper, tissues, or specialized laboratory membranes.
Blotting is a fundamental physical and chemical process that centers on the principle of absorption without friction. Unlike wiping, which involves moving a material across a surface to displace liquid, blotting involves pressing an absorbent material directly onto a surface to pull liquid into the material's fibers. This distinction is crucial in contexts where the surface is delicate or where the pattern of the liquid must be preserved or transferred precisely. In everyday life, we encounter blotting when we use a napkin to remove excess oil from a slice of pizza or when a calligrapher uses specialized paper to ensure that wet ink does not smudge across the page. The essence of blotting is the vertical application of pressure, utilizing capillary action to draw moisture upward and away from the substrate.
- Daily Utility
- In the world of cosmetics, blotting is a standard technique for managing skin oils. Individuals with oily skin types often use small, portable 'blotting papers' to dab their T-zone. This removes shine without disturbing the underlying makeup, a feat that wiping could never achieve.
After applying the deep red lipstick, she performed a quick blotting with a tissue to ensure the color stayed matte and didn't bleed onto her teeth.
- Scientific Precision
- In molecular biology, blotting is a sophisticated laboratory technique. It involves the transfer of macromolecules—DNA, RNA, or proteins—from a gel matrix onto a solid carrier membrane, such as nitrocellulose or PVDF. This 'blot' allows researchers to identify specific molecules using probes or antibodies, which would be impossible while the molecules are still trapped inside the gel.
The term extends into the culinary arts and restoration as well. When cleaning a vintage rug, a professional will always recommend blotting a wine stain rather than scrubbing it. Scrubbing forces the liquid deeper into the fibers and damages the pile, whereas blotting lifts the liquid out. Similarly, in professional kitchens, blotting meat with paper towels before searing is the secret to achieving a perfect Maillard reaction; any surface moisture would otherwise turn to steam, preventing the meat from browning properly. Thus, blotting is a technique of restraint and precision, utilized across diverse fields to manage liquids with care.
The scientist monitored the blotting process carefully, ensuring the buffer solution moved through the stack by capillary action to transfer the DNA fragments.
Art restoration requires gentle blotting to remove centuries of grime without stripping away the original pigment.
- The Physics of Absorption
- The effectiveness of blotting depends on the porosity of the material used. High-quality blotting paper is unsized, meaning it lacks the coating found on writing paper that prevents ink from spreading. This allows the paper to act like a sponge on a microscopic level.
The chef's technique of blotting the scallops resulted in a golden-brown crust that was the highlight of the meal.
In forensic science, blotting can be used to recover faint impressions of fluids at a crime scene.
Using 'blotting' correctly requires understanding whether you are referring to the physical act of drying or the specific scientific methodology. As a gerund (a noun formed from a verb), it often functions as the subject or the direct object of a sentence. For instance, 'Blotting is essential for clean calligraphy.' Here, it describes the general action. In more complex sentences, it often appears alongside the material being used, such as 'blotting paper' or 'blotting pads.' When used in a scientific context, it is frequently modified by specific names like Southern, Northern, or Western to indicate the type of molecule being analyzed. The verb form 'to blot' is the root, but 'blotting' as a noun captures the entire procedure or technique.
- Grammatical Context
- Blotting can act as a modifier for nouns (e.g., blotting paper) or as a stand-alone noun representing a process (e.g., 'The blotting took three hours'). It is almost always uncountable when referring to the technique in general.
The lab technician spent the afternoon performing Western blotting to detect the presence of the target protein in the patient samples.
- Everyday Examples
- 'Gentle blotting of the wound is better than rubbing it with a towel.' This sentence highlights the procedural aspect of the word in a first-aid context.
In creative writing, 'blotting' can be used metaphorically or descriptively to evoke a sense of absorption or erasure. 'The heavy fog was blotting out the lighthouse' uses the verb form, but 'The blotting of the sun by the clouds' uses the noun form to describe an atmospheric event. However, the most common usage remains the literal act of liquid removal. Whether you are discussing the maintenance of a fountain pen or the sophisticated analysis of DNA, the word carries a connotation of deliberate, careful action. It implies a level of attention to detail that 'drying' or 'cleaning' does not quite capture.
The architect used a special blotting technique to create the soft, textured appearance of the watercolor sky.
Success in the experiment required the consistent blotting of the membrane to prevent background noise in the results.
- Common Collocations
- Frequent pairings include 'blotting paper', 'blotting membrane', 'blotting technique', and 'blotting action'. These phrases specify the tool or the method used.
The constant blotting of his forehead with a handkerchief revealed how nervous the witness actually was.
After the spill, immediate blotting with a clean cloth saved the expensive silk upholstery from permanent damage.
You are most likely to encounter 'blotting' in three distinct environments: the science laboratory, the beauty salon, and the art studio. In the lab, it is a daily task for biologists. You might hear a researcher say, 'I need to set up the Southern blotting overnight.' This refers to a very specific, technical sequence of events. In the beauty world, makeup artists and skincare enthusiasts use the term frequently. If you watch a makeup tutorial on YouTube, the creator might advise, 'Instead of rubbing your face, try blotting with a tissue to remove excess foundation.' This usage is ubiquitous in the fashion and cosmetics industry, where maintaining the integrity of a 'look' is paramount.
- Professional Settings
- In printing and publishing, blotting is discussed in the context of ink drying times. High-speed presses must manage the blotting of ink into the paper to ensure sharp images. In medical settings, nurses use blotting to clean around sensitive surgical sites.
The museum curator explained that the blotting of the ancient manuscript required a specialized chemical-free absorbent paper.
- Cultural References
- In historical dramas or literature set in the 19th century, you'll often see characters using a 'blotter' on a desk. This was a heavy piece of wood or metal with blotting paper attached, used to dry handwritten letters before folding them.
Furthermore, 'blotting' is a key term in the cleaning industry. Professional cleaners are trained in 'blotting techniques' for stain removal. You will hear this word in instructional videos for home maintenance or on the back of cleaning product labels. It is also a term used in the food industry, particularly in quality control. For example, fried snacks might undergo a blotting process to meet health standards regarding oil content. Even in casual conversation, someone might say, 'I'm just blotting my brow,' to indicate they are dabbing away sweat during a hot day. The word is versatile, bridging the gap between high-level science and everyday hygiene.
During the high-stakes interview, the candidate kept blotting his palms on his trousers to hide his perspiration.
The tutorial emphasized that blotting the excess oil from the surface of the soup would improve both the presentation and the flavor.
- Academic Context
- Students in introductory biology courses will encounter blotting when learning about electrophoresis and genetic sequencing. It is a 'gatekeeper' term that signals a transition into more advanced laboratory methods.
The artist's blotting of the wet paint created a unique stippled effect that added depth to the landscape.
In high-end tailoring, blotting with steam is used to shape delicate fabrics without crushing the weave.
The most frequent mistake made with the word 'blotting' is confusing it with 'wiping' or 'rubbing.' While all three actions involve removing liquid, the mechanics are vastly different. Wiping involves horizontal motion, which can smear ink, damage delicate membranes, or push stains deeper into a carpet. Blotting is strictly vertical. Another common error occurs in the spelling and usage of 'blotting paper.' Learners often forget the double 't,' or they use the word 'bloating' (which means swelling) by mistake. This can lead to humorous but confusing sentences, such as 'I used bloating paper for my ink.' Always double-check the 't' count!
- Scientific Misnomers
- In a lab setting, a common mistake is failing to specify the type of blotting. Saying 'I did a blot' is often too vague. Professionals expect you to specify if it was a Western, Southern, or Northern blot, as the equipment and chemicals required are entirely different.
Incorrect: He was blotting the table with a sponge to clean up the spilled milk. (Correct: Wiping, unless he was dabbing a specific spot without moving the sponge).
- Contextual Confusion
- Learners sometimes use 'blotting' when they mean 'masking.' Blotting removes liquid that is already there, while masking prevents liquid from reaching a surface in the first place.
In the context of the phrasal verb 'blot out,' people sometimes use 'blotting out' incorrectly when 'blocking' or 'covering' would be more appropriate. 'Blotting out' implies a total and somewhat messy erasure, like an ink stain covering words. If you are just standing in front of the TV, you are 'blocking' the view, not 'blotting it out.' Using 'blotting' for simple drying is also technically correct but might sound overly formal. If you are just drying your hands with a towel, 'drying' is the standard term. 'Blotting' suggests you are being particularly careful not to irritate the skin or damage the towel.
Incorrect: The tall building was blotting the sunlight. (Better: Blocking, unless the building is somehow absorbing the light like ink).
Correct usage: The thick black ink was blotting out the sensitive information on the document.
- Spelling Tip
- Think of 'blot' as a short, sharp action. The double 't' in 'blotting' reflects the extra effort needed to absorb the liquid.
In lab reports, students often confuse 'blotting' with 'staining.' Blotting is the transfer; staining is the coloring that happens afterward.
Avoid saying 'blotting the floor' if you are using a mop. Moping involves a different physical motion entirely.
While 'blotting' is a specific term, there are several synonyms and related words that might be more appropriate depending on the level of intensity or the medium involved. 'Dabbing' is the closest everyday synonym. It implies the same light, vertical touch but is less technical. You 'dab' your eyes with a tissue when crying, but you 'blot' a scientific membrane. 'Sapping' or 'soaking' describes the absorption but focuses more on the liquid's movement than the physical action of the person. Understanding the nuances between these terms can help you sound more like a native speaker.
- Blotting vs. Dabbing
- Blotting is more systematic and often involves a specific material (like blotting paper). Dabbing is more casual and can be done with anything, including a fingertip.
- Blotting vs. Wiping
- Wiping uses friction and lateral movement. Blotting uses pressure and vertical movement. Use wiping for cleaning a counter; use blotting for a fresh ink stain.
- Blotting vs. Absorbing
- Absorbing is the result; blotting is the action. The paper absorbs the ink because of your blotting.
Rather than blotting the spill, he tried to scrub it, which only made the carpet stain larger.
In a technical or scientific context, you might use 'electroblotting' if electricity is used to speed up the transfer process. In art, 'stippling' is a related technique where you apply small dots, sometimes by blotting a sponge onto the canvas. If you are removing moisture from food, you might use 'patting dry,' which is a synonym for blotting but specifically used for cooking (e.g., 'pat the chicken dry before roasting'). Knowing when to switch from 'blotting' to 'patting dry' or 'dabbing' shows a high level of linguistic nuance.
The nurse recommended blotting the area with a sterile gauze pad rather than using a cotton ball which might leave fibers.
The archival process for old photographs involves careful blotting of any chemical residue to prevent yellowing over time.
- Vocabulary Expansion
- Consider 'leaching' if the liquid is being drawn out by a chemical process, or 'wicking' if the material is drawing the liquid away automatically without manual pressure.
The high-performance fabric was designed for moisture-wicking, which is essentially a continuous, automatic blotting action for athletes.
The detective noticed the blotting of the ink on the ransom note, suggesting it had been written in a hurry and dried with a napkin.
How Formal Is It?
豆知識
Before blotting paper was common, people used 'pounce'—a fine powder made from sand or crushed bone—to dry ink on parchment. Blotting paper was actually discovered by accident when a paper mill forgot to add the 'sizing' (glue) to a batch of paper, making it useless for writing but perfect for absorbing ink.
発音ガイド
- Pronouncing it like 'bloating' (with a long 'o').
- Forgetting the double 't' when spelling.
- Confusing the 'bl' sound with 'pl' (plotting).
- Not using the flap 't' in American English, making it sound overly formal.
- Dropping the 'g' at the end (blottin').
難易度
Easy to understand in context but technical in science.
Requires correct spelling (double 't') and understanding of gerund use.
Common enough in daily life (makeup, spills) to be useful.
Can be confused with 'plotting' or 'bloating' if not careful.

語源
The word 'blotting' comes from the Middle English 'blot', which likely originated from the Old French 'blote', meaning a clod of earth or a lump. It entered the English language in the 14th century to describe a spot or a stain. The specific use of 'blotting' to describe the absorption of liquid developed alongside the invention of unsized paper in the 15th century.
元の意味： A physical lump or a spot of dirt/ink.
Germanic/Romance mix (Old French influence on Middle English).文化的な背景

よくある質問
10 問Wiping uses friction and horizontal movement to move liquid away, which can cause smearing. Blotting uses vertical pressure to pull liquid directly into an absorbent material, preventing it from spreading. For example, you blot a wine stain but wipe a dusty table.
It is named after its inventor, Edwin Southern, who developed the technique for DNA transfer in 1975. Other techniques like Northern and Western blotting were named as a play on his last name.
Yes, a towel can be used for blotting, but it must be absorbent. For delicate tasks like makeup or calligraphy, specialized blotting paper or tissues are better because they don't leave fibers behind.
It can be both. As a gerund, it acts as a noun (e.g., 'Blotting is helpful'). It can also be the present participle of the verb 'to blot' (e.g., 'She is blotting the ink').
It is usually made from cotton or other high-cellulose fibers and is 'unsized,' meaning it doesn't have the protective coating that regular paper has, allowing it to absorb liquid easily.
Blotting is most effective on fresh, wet stains. Once a stain has dried, blotting will not be very effective, and other cleaning methods like scrubbing or chemical treatment may be needed.
Take a small piece of blotting paper and press it gently against the oily areas of your face, like your forehead and nose. Hold it for a few seconds and then lift it straight off without rubbing.
Blotting moisture off the surface of meat or fish allows it to brown properly in the pan. If there is water on the surface, it will turn to steam, and the food will boil instead of searing.
Metaphorically, it means to completely hide or erase something from view or memory. For example, 'The clouds blotted out the sun' or 'He tried to blot out the memory of the war.'
Yes, forensic scientists use blotting to transfer latent prints or biological fluids from a crime scene to a medium that can be analyzed in the lab.

Summary
Blotting is the precise act of dabbing to absorb liquid or transfer molecules without smearing. For example, 'Blotting the stain prevented it from spreading across the white silk dress.'
- Blotting is the careful absorption of liquid using vertical pressure, common in cleaning and art.
- In molecular biology, it is a key technique for transferring DNA, RNA, or proteins to a membrane.
- It differs from wiping because it avoids friction, preventing smearing or damage to delicate surfaces.
- Commonly used tools include blotting paper, tissues, or specialized laboratory membranes.
Always Blot Fresh Spills
When you spill something on a carpet, grab a cloth and blot immediately. If you rub it, the liquid will go deeper into the fibers and become a permanent stain.
Blot Your Lipstick
After applying lipstick, blot with a tissue and then apply a second layer. This helps the color last much longer and prevents it from smudging.
Dry Your Meat
For a restaurant-quality steak, use paper towels for blotting all the moisture off the meat before it hits the hot pan. This ensures a perfect crust.
Texture with Blotting
You can create cool textures in watercolor paintings by blotting wet paint with a crumpled tissue or a sea sponge.
