Abstract:The identification of high-energy compounds in trace concentrations not only in the laboratory, but also in field conditions is of particular interest. The process should be clear, easy, and well-recognizable. We formed SERS-active substrates by using elongated nickel nanotubes synthesized by electrochemical deposition in the pores of ion-track membranes and coated them with gold for further application in the detection of low concentrations of analytes. The substrates were characterized using various techniqu… Show more
“…8,9 Since SERS and SEIRA spectra are strongly affected by the way how the molecule adsorbs on the metal surface, these techniques provide control over what occurs on the metal nanosurfaces. [10][11][12][13] By analyzing the well-known surface selection rules that govern surface-enhanced vibrational spectra, it is possible to understand the appearing spectral patterns for molecules immobilized on the metal surfaces. Briefly, SERS molecular bands attributed to the modes with polarizability derivative components normal to the metal nanosurface dominate in the spectrum.…”
The combination of nanospectroscopic, gravimetric, and electrokinetic methods made it possible to determine the adsorption process of the erlotinib layer on AgHHNP monolayers (considered as drug nanocarriers) qualitatively and quantitatively.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
