Gene therapy nanofilm
Recently, the research team of Dr. David M. lynn of the University of Wisconsin in the United States has developed a new tool nano-film that can solve the problem of transporting tools or materials for genetic modification during gene therapy.
The study found that it used to wrap dna and water-soluble polymer molecules, so it can slowly release from the surface into the tissue, the researchers also tried to wrap the film in an implantable material like a vascular stent. The surface, then the drug wrapped in the film, can be released into the blood vessels at a very slow rate, to avoid the like inflammatory reaction, or blood coagulation effect. The scientists involved in the study said that the nano-film should be able to be used, and the polymer coating is an important key, because the short-chain gene therapy dna should be slowly released, the nano-film should be thin enough, and Different organizations and different medical uses have to design coatings with wide applicability, so the subsequent related work has yet to be overcome.

Because the treatment is to introduce human normal genes or therapeutic genes into human target cells in a certain way to correct the defects of the genes or play a therapeutic role, thereby achieving the biomedical high technology for the purpose of treating diseases. Gene therapy differs from conventional treatments in that it targets the root cause of the disease—the abnormal gene itself. In gene therapy, scientists hope to eliminate the need for drugs, but only use the way to correct the genes to solve the disease. -------Information from: Shanghai Medical Devices

This is a visual rehabilitation device. It has the function of history storage.  In order to facilitate the use of training again, users can store the training mode.  Next time,  the training mode only needs to be called. Our products have two dimensional vision tracking and circular vision tracking
