Adhesive Vaccine Polyvinylpyrrolidone, Replacing Injections

 Kasisia Savik, a biomedical engineer at the University of Stony Brook America,

made a polyvinylpyrrolidone-based skin adhesive that injects the solution to the vaccine without using ampoules.
Skin does not easily absorb large molecules, but polyvinylpyrrolidone was able to extract water from its skin due to its water-loving nature. When the moisture returned to the skin, the outer layer of the skin swelled and caused the molecules larger than usual to enter it.
ImmunoMatrix adhesive can be vaccinated without skin irritation and without pain, and affects on how it can deliver the vaccine to the body, especially during the onset of epidemic outbreaks.
Over the years, the engineer completed a process that included the combination of the polymer with the vaccine solution. As a result, the polyvinylpyrrolidone polymer converts this solution into nano-fibers with a larger surface area and also compresses these fibers. In experiments on mice and human skin, the glue consisting of these dense fibers delivered molecules of the vaccine, 250 times larger than the molecules that normally absorbs the skin, and did not require any cutting.
