Aqueous platinum nanoparticles solution for the detection of pyridine derivatives of aminophosphinic acid. Influence of positional isomerism
Source abstract
Abstract
Abstract Unsupported platinum nanoparticles (PtNPs) (∼12 nm in diameter) were synthetized by the polyol method and ultraviolet-visible spectroscopy (UV–vis), scanning electron microscope (SEM), and X-ray powder diffraction (XRD) characteristic of their agglomerates were examined. Then, three pyridine α−aminophosphinic acid isomers (α–, β –, and γ –) were synthetized and assembled on the surface of PtNPs. Differences in adsorption and thus, in the spectral response resulting from positional isomerism, were checked by surface-enhanced Raman scattering (SERS) at 785 nm excitation wavelength. The manner of interaction of the investigated isomers with PtNPs were discussed and compared. General conclusions were drowned.
