Raman spectra of rhodamine 6g

WebbRhodamine 6G (Rh6G) dye is tested comparatively for positively and negatively charged Au NPs prepared by the reduction of chitosan and citric acid, respectively. The adsorption of Rh6G is found to be weaker on the positively charged Au NPs, whereas more substantial aggregation is found on negatively charged Au NPs. WebbGold nanoparticles (AuNPs) and their growth by seed method: size estimation from the SPR band and SERS detection Objectives 1. To synthesize gold nanoparticles by citrate reduction.
