British scientists have developed new nanoprobes

Release date: 2008-10-24

Researchers at the London Nanotechnology Center recently developed a new type of nanoprobe that can be used to detect whether an antibiotic drug can bind to bacteria, thereby attenuating or eliminating the ability of bacteria to destroy the human body. the goal of.
In the process of treating people with antibiotics, the bacteria causing the disease are prone to drug resistance, which makes the antibiotics lose their efficacy. The principle of action of antibiotics is to destroy the structure of the cell wall after binding to the cell wall of the pathogenic bacteria, causing the pathogenic bacteria to die. Once the drug resistance is produced, the cell wall structure of the bacteria changes, the cell wall becomes thick, and the antibiotic cannot bind to the cell wall. The researchers covered a row of nanoprobes that covered the proteins that make up the bacterial cell wall. Once the antibiotic binds to the cell wall, the surface weight of the probe increases, and this surface pressure causes the nanoprobe to bend.
Researchers have studied the vancomycin drug and found that the cell wall hardness of drug-resistant bacteria is 1000 times that of non-resistant bacteria. Therefore, nano-probes are used to detect the structural changes of bacterial cells in various cell walls, and the antibiotics with the greatest destructive effect on pathogenic bacteria are screened. This is the first time scientists have applied nanoprobes to drug screening. The preliminary results of related experiments are published in the latest issue of Nature-Nanotechnology. ——Shanghai Medical Device Industry Association

With more than 18`s years excellent business for Food Grade Hyaluronic Acid Powder, Hi-Tech has great reputation with Superior quality China Food Grade Hyaluronic Acid, More competitive price and Thoughtful customer service.

Hi-Techâ„¢ Food Grade Powder Supplier, the Hyaluronic Acid is available in variety of salt forms, while sodium salt is the most commonly commercial product called sodium hyaluronate, habitually called hyaluronic acid, or HA.

The content of hyaluronic acid in body will decrease as they are aging, oral hyaluronic acid supplementation can supplement HA in body and improve skin conditions, moisturizing skin from the inside out, smoothing out wrinkles during cell metabolism. Oral hyaluronic acid Supplementation is very popular in Japan, USA and other western countries.

The Oral Sodium Hyaluronate can support Sodium Hyaluronate levels in the body. It can help people have full energy and youthful vigor. Besides, oral Sodium Hyaluronate is useful in maintaining skin elasticity by moisturizing the skin from the dermis to epidermis. Sodium Hyaluronate is also an impressive pain reliever. It can help people ease the injury of joints, especially their knees. Sodium Hyaluronate along with other ingredients including collagen, vitamins, Chondroitin Sulfate, glucosamine, and plant extracts can make tablets, capsules and oral solution which are good for skin care and joints care.

Nutritional Supplements

Hyaluronic acid extracted from rooster combs cannot be absorbed by the intestinal tract. But, Japanese scientists have developed a proprietary enzyme-cleaving technique to lower the molecular weight of hyaluronic acid without altering its chemical nature. This allows hyaluronic acid to be taken orally as a nutritional supplement, many varieties of which are readily available for commercial use.
