AbstractResults of studies on the analytical capabilities of gold nanoparticles in the methods of optical molecular absorption spectroscopy are reported. Peculiar effects of the nature of nanoparticle stabilizer, its charge, morphology of nanoparticles, form in which they are present in the system (in a colloidal solution or as a part of a nanocomposite with polyurethane foam) upon the determination of organic compounds (thiols, cationic compounds, catecholamines) and inorganic anions are considered. The determination is based on aggregation of nanoparticles or change in the state of their surface and morphology as a result of silver coating, leading to significant spectral and color changes, which can be monitored both by optical molecular absorption spectroscopy and visually. The ways to increase sensitivity and to control selectivity of the analysis using gold nanoparticles and their nanocomposites are outlined.
