Investigators from Chonbuk National University Zero in on Nanoparticles

June 27, 2014

By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Nanoparticles have been presented. According to news reporting originating in Jeonju, South Korea, by NewsRx journalists, research stated, "The cultural filtrates of Klebsiella pneumoniae cultured under normal gravity and low shear modeled microgravity were potentially used to biosynthesize gold nanoparticles using the precursor gold III chloride trihydrate. The gold nanoparticles produced were spherical, of size between 16-36 and 24-50 nm with the cultural filtrates of normal and low shear modeled microgravity respectively."

The news reporters obtained a quote from the research from Chonbuk National University, "The characteristic plasmon resonance of gold nanoparticles occurred between 535-550 nm in the spectral analysis. XRD reflections (1 1 1), (2 0 0), (2 2 0), (3 1 1) indicate the face centered cubic and crystalline nature of the biosynthesized gold nanoparticles. The FTIR study proposes that proteins excreted into the cultural filtrate were involved in the synthesis and stabilization of gold nanoparticles."

According to the news reporters, the research concluded: "The in vitro cytotoxicity on 3T3L1, H9c2 and HepG2 cell lines showed the nontoxic and biocompatible nature of biosynthesized gold nanoparticles."
