Reports from Korea Research Institute of Bioscience and Biotechnology Advance Knowledge in Bovine Serum Albumin

February 25, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Proteins is the subject of a report. According to news reporting originating in Taejon, South Korea, by NewsRx journalists, research stated, "Morphology control of gold nanocrystals was successfully carried out via a modified polyol process using bovine serum albumin (BSA) as a surface regulating biopolymer."

The news reporters obtained a quote from the research from the Korea Research Institute of Bioscience and Biotechnology, "By combining a small amount of AgNO3 as an additive, BSA yielded regular Au octahedrons, cubes, and higher polygons owing to the underpotential deposition of Ag species onto {100} facets. Unexpectedly, a uniform tetrahexahedral morphology that had high-index facets of {740} and {210} on the surface was formed at a relatively high concentration of AgNO3 with BSA, and was due to the coordination power of BSA to a gold surface weaker than that of poly(vinyl pyrrolidone)."

According to the news reporters, the research concluded: "The resulting gold polyhedrons were aggregated after the synthesis because of the partial denaturation of BSA, but the simple surface exchange with 11-mercaptoundecanoic acid enabled a stable dispersion in aqueous solution."
