Detection of vasodilator drugs through microwave spectroscopy of Au NP colorimetric probes using a microwave metallic photonic crystal-inspired resonant probe

Abstract

A low-cost, time-effective and easy-to-use novel analytical technique incorporating microwave spectroscopy of unmodified gold nanoparticles for the detection of selected vasodilator drugs.

Benzimidazole-Based Imine-Linked Copper Complexes in Food Safety: Selective Detection of Cyproheptadine and Thiabendazole

“…It has been observed that the consumption of pharmaceutical products by living organisms and their disposal in the environment has increased gradually. − Disposal of unused medication into the environment is considered to be the major source for the occurrence of pharmaceutical waste in the environment. − Owing to the negative potential effects that they cause to the environment, special attention has been focused for the estimation of such residues. In this regard, Zhang et al reported the matrix effects for the evaluation of various pharmaceutical residues in seawater using UHPLC or CID MS-MS methods .…”

“…In another work, Lad et al detected two vasodilator drugs, i.e., amlodipine besylate and minoxidil, using hybrid gold nanoparticles. They proposed aggregation of gold nanoparticles upon binding with drug molecules as the binding mechanism . In other study, silica-coated reverse-phase column chromatography was employed by Paull et al for the determination of pharmaceutical residues in environmental samples .…”
