General description

PVP has biocompatibility, low toxicity, adhesive characteristics, complexing stability, relatively inert behavior, and is resistant to thermal degradation. It is readily prepared by the polymerization of N-vinyl-2-pyrrolidone or by Reppe synthesis technique.[1]

Application

PVP is one of the constituents used in the synthesis and coating of silver nanocubes.[2][3] It serves as a reducing agent[4] and colloidal stabilizer[5] in the synthesis of palladium nanobars,[6][5] triangular,nanoplates,[7]twinned nanorods and bipyramids.[8] It is also used as a capping agent in the synthesis of silver nanospheres,gold nanoframes.[9] General applications of PVP are: in pharmaceutical, food, beverage, cosmetic, toiletry and photographic industries.[1]

Other Notes

Polyvinylpyrrolidone is a component of Denhardt′s Solution and is included at a concentration of 1% (w/v) in the standard 50X stock solution.
