Preparation of reagent indicator papers with silver triangular nanoplates for the purposes of chemical analysis

Abstract

An impregnation method of preparation of reagent indicator papers with silver triangular nanoplates (TNP) was developed. Conditions of the modified papers preparation (type of paper, way of TNP putting, conditions of drying) allowing for acceptably uniform distribution of TNP were chosen. Spectral characteristics of prepared materials were studied. Presence of an intense TNP surface plasmon resonance band in diffuse reflectance spectra of the modified papers which is linearly related to the content of TNP in the samples as well as lability of its position and shape in presence of some substances gives rise to prospects of using prepared materials as test-tools in the chemical analysis.
Key words: reagent indicator paper, silver triangular nanoplates, surface plasmon resonance, test-tool, diffuse reflectance spectroscopy.
