Recent Research from Chinese Academy of Sciences Highlight Findings in Analytical Chemistry (Wet-Chemical Enzymatic Preparation and Characterization of Ultrathin Gold-Decorated Single Glass Nanopore)

By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Analytical Chemistry is now available. According to news reporting originating in Beijing, People's Republic of China, by NewsRx journalists, research stated, "The conical glass nanopore was modified through layer-by-layer electrostatic deposition of a monolayer of glucose oxidase, and then an ultrathin gold film was formed in situ through enzyme-catalyzed reactions. The morphology and components of single glass nanopore before and after ultrathin Au deposition were characterized by transmission electron microscopy (TEM) and energy-dispersive X-ray (EDX) analysis, respectively."

The news reporters obtained a quote from the research from the Chinese Academy of Sciences, "In particular, the quenching of the quantum dots fluorescence in the nanopore tip zone further illustrated that the gold nanofilm was successfully deposited on the inner wall of the single glass nanopore. The Au thin films make the glass nanopores more biologically friendly and allow the nanopores facile functionalization of the surface through the Au S bonds."

According to the news reporters, the research concluded: "For instance, the ionic current rectification (ICR) properties of the gold-decorated glass nanopores could be switched readily at different pHs by introducing different thiol molecules."
