CuAAC-mediated Au NPs-implemented nanosensors for detection of reducing agents. (A) CuAAC-mediated nanosensor for detection of the whole protein in which azide-Au NPs and alkyne-Au NPs are triggered to aggregate by CuAAC with the protein and Cu (II). (B) Naked-eye-based colorimetric detection of OPs using CuAAC (OPs: organophosphate pesticides; Au: gold nanoparticles; AChE: Acetylcholineesterase; ATCl: acetylthiocholine; CuO: CuO nanoparticles). (C) CuAAC-mediated nanosensor for detection of the ascorbic acid which can reduce Cu (II) into Cu(I). (D) CuAAC-mediated nanosensor for detection of NO(g) which can reduce Cu(II) to Cu(I) in the redox reaction. Adapted with permission from [73, 89, 90, 91].
