Measurement of biological aminothiols (e.g., cysteine, homocysteine and glutathione) is important for clinical diagnosis. There is growing interest in the fabrication of optical nanoprobes due to their high sensitivity, low cost, low-power requirements and high biocompatibility.We give a general overview of the different strategies for gold nanoparticle (AuNP)-based optical probes for sensing aminothiols, including colorimetric, fluorescent, resonance-light scattering, chemiluminescent and surface-enhanced Raman scattering techniques.This review also summarizes these optical probes in terms of analytical performance, and discusses possible solutions to overcome some critical challenges facing these methods.
► Recent advances using gold-nanoparticle-based optical probes for aminothiols.
► Gold nanoparticles as colorimetric probes for aminothiols.
► Gold nanoparticles as fluorescent probes for aminothiols.
► Gold nanoparticles as resonance-light scattering probes for aminothiols.
► Gold nanoparticles as chemiluminescent probes for aminothiols.
