Reports on Scleroproteins Findings from Chungnam National University Provide New Insights (Preparation and Characterization of Gelatin Nanofibers Containing Silver Nanoparticles)

By a News Reporter-Staff News Editor at Science Letter -- New research on Proteins is the subject of a report. According to news reporting originating in Taejon, South Korea, by NewsRx journalists, research stated, "Ag nanoparticles (NPs) were synthesized in formic acid aqueous solutions through chemical reduction. Formic acid was used for a reducing agent of Ag precursor and solvent of gelatin."

The news reporters obtained a quote from the research from Chungnam National University, "Silver acetate, silver tetrafluoroborate, silver nitrate, and silver phosphate were used as Ag precursors. Ag+ ions were reduced into Ag NPs by formic acid. The formation of Ag NPs was characterized by a UV-Vis spectrophotometer. Ag NPs were quickly generated within a few minutes in silver nitrate (AgNO3)/formic acid solution. As the water content of formic acid aqueous solution increased, more Ag NPs were generated, at a higher rate and with greater size. When gelatin was added to the AgNO3/formic acid solution, the Ag NPs were stabilized, resulting in smaller particles. Moreover, gelatin limits further aggregation of Ag NPs, which were effectively dispersed in solution. The amount of Ag NPs formed increased with increasing concentration of AgNO3 and aging time. Gelatin nanofibers containing Ag NPs were fabricated by electrospinning. The average diameters of gelatin nanofibers were 166.52 +/- 32.72 nm, but these decreased with the addition of AgNO3."

According to the news reporters, the research concluded: "The average diameters of the Ag NPs in gelatin nanofibers ranged between 13 and 25 nm, which was confirmed by transmission electron microscopy (TEM)."
