By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Biological Factors have been presented. According to news reporting originating in Wuhan, People's Republic of China, by NewsRx journalists, research stated, "We report on the fabrication of hybrid films of gold nanoparticles (AuNPs) and [tetrakis (N-methylpyridyl) porphyrinato] cobalt (CoTMPyP) based on electrostatic layer-by-layer (LBL) self-assembly technique. A three-dimensional nanostructured film composed of positively charged CoTMPyP and negatively charged poly(acrylic acid)-stabilized AuNPs can be formed onto various substrates, including 4-aminobenzoic acid modified glassy carbon electrode, 11-mercaptotroponic acid modified gold film, and quartz plate with negatively charged surface."
The news reporters obtained a quote from the research from the Huazhong University of Science and Technology, "The regular growth of hybrid films is investigated by UV-vis spectroscopy, surface plasma resonance, and impedance spectroscopy. The prepared multilayer films possess flexible electro-catalytic activity toward O-2 reduction reaction. It is noted that the electro-catalytic capability of the prepared multilayer film decreases as bilayer number increases."
According to the news reporters, the research concluded: "The unexpected observation of catalytic activity with bilayer number is investigated in detail."
