Heal yourself like a Wolf

American scientists at the University of California at Riversiside (UCR-USA) have succeeded in making a new material from the patient's own blood to heal chronic wounds.

This new gel is manufactured using multi-platelet plasma (PRP) technology , which works by increasing the self-healing function of the patient's wound. Protein (thrombin) in the blood is removed to activate platelets and enhance tissue regeneration. After that, the scientists added vitamin C to create the gel, because vitamin C is thought to be the most important in the process of making collagen to help heal quickly.

The properties of this gel are also very soft and capable of stretching like rubber, even stretching up to 50 times the original size. After being cut off, it is able to heal itself after about 24 hours, just like how Logan, or the Wolverine werewolf in the X-Men series, heals itself on the body.

The gel is also capable of being an electrical conductor through ionic flow, meaning that the material allows ions (charges) to pass through. This is also the first time in the scientific world, researchers integrate the ability to self-recover in a gel-like substance that is a conductor . Thereby, the University of California scientists used bipolar ions to hold the molecules together, in which each molecule has a positive and negative terminal. The voltage imbalance between them creates an electrostatic attraction. After that, mixing salt with high ions with a flexible polymer molecule to create a material like gel that heals wounds.

The gel is also capable of being an electrical conductor through ion flow.

The British National Health Service (NHS) in collaboration with the Biotherapy Services Company conducted a test on the above gel for patients treated for chronic wounds at Croydon University Hospital for results 9 / 10 patients had recovered after using this gel, although they had been ineffective for years. According to Dr. Stella Vig of this hospital, it is because this new gel is isolated from the blood of patients so it can reduce the risk of allergy compared to conventional methods and shorten the duration of treatment, as well as The effect is very high.

It has just been published in Advanced Materials, but American scientists' early research is highly appreciated by its multi-dimensional potential application. This new gel will provide the robot with the ability to restore itself after a technical problem occurs, or extend the life of the Li-ion battery used for electric vehicles and electronics, improve the birth sensor. study in the field of health or environmental monitoring."Over the years, the creation of a new material that is full of these features has made it difficult for many scientific researchers. Now we have made and its potential applications. just started to be discovered , " said Dr. Chao Wang, a member of the research team.

Because this new gel is isolated from the patient's blood, it may reduce the risk of allergy compared to conventional methods.

In addition to the gel of American scientists, scientists from the Himalayan Biological Resources Technology Institute and the Institute of Scientific and Patent Research in New Delhi (India) have also successfully developed new compounds from Cellulose fibers of bamboo combined with silver nanoparticles can effectively heal skin wounds.

Accordingly, composite nanomembranes were synthesized by inserting silver nanoparticles into the framed section of cellulose nanocrystals, which were extracted from bamboo leaves. After incubation with bacterial infection, nanocomposite membranes prevent bacteria from reproducing by securing silver nanoparticles clinging to the cell membrane and gradually destroying the structure of bacterial cells.
