Australian scientists have developed a patch nanovystupami that can be an alternative to injections for administration of large molecules such as antigens in vaccines, reports Daily Mail. Patch about two inches in diameter, was developed by scientists at the University of Queensland, Australia, it is enough for a couple of minutes to adhere the drug penetrate the skin. The principle of operation is that the vaccine molecules located on the surface of the nanoparticles of the adhesive side of the patch to cover and to overcome the protective layer of the skin. In animal studies with the vaccine patch was even better injection. According to the Head of Development Professor Mark Kendall (Mark Kendall), may be the reason that the vaccine, which was introduced by the patch immediately below the surface of the skin penetrating where. A number of immune cells, and causes a stronger immune response In addition, the vaccine may be in the form of a patch is lifted, that it can be applied by the patient, it does not freeze, if necessary, can be sent by post, and eliminates the risk of infection when injected. Necessary for the occurrence nanoplastyrya pharmaceutical research about the effectiveness and safety of persons. It is assumed that nanoplastyr be effectively used for vaccination against influenza and to combat epidemics in third world countries.
