By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Nanoparticles have been presented. According to news reporting out of Beijing, People's Republic of China, by NewsRx editors, research stated, "In plants, Photosystem I (PSI) is composed of a core complex and a membrane-associated antenna complex light-harvesting complex I that captures light and funnels its energy to the core complex. To obtain Raman structural information on -carotenes embedded in the PSI core complex, a sandwich' system of roughened silver slice: target protein complexes: single silver nanoparticles was fabricated for Surface-Enhanced Resonance Raman Scattering (SERRS) measurements."
Our news journalists obtained a quote from the research from the Chinese Academy of Sciences, "This study provided a method to overcome spectral irreproducibility, which is the main drawback of Surface-Enhanced Raman Scattering/SERRS-based studies. The Raman spectra of -carotenes embedded in the PSI core complex can be obtained at very low sample concentrations (1-5 mu g Chl/ml) and high signal/noise ratios. The -carotenes in the spinach PSI core complex were predominantly all-trans configuration. The membrane protein-mediated adsorption of silver nanoparticles induced the uniform distribution of a large number of single nanoparticles, which contributed to achieving highly reproducible SERRS spectra."
According to the news editors, the research concluded: "This study is the first to apply single silver nanoparticle-based SERRS analysis in membrane proteins."
