Schematic illustration of colorimetric detection based on oxidation by peroxidase‐like NMs. A) Scheme of oxidizing peroxidase substrates by various peroxidase‐like NMs. B) Schematic to detect S. typhimurium using aptamer‐adsorbed MNPs. C) Detection of influenza (H3N2) virus using a nanohybrid of CNTs and Au NPs, and norovirus‐like particles in human serum using a nanohybrid of graphene and Au NPs. MNP: magnetic nanoparticle; TMB: 3,3′,5,5′‐tetramethyl‐benzidine; ABTS: 2,2′‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid); CNT: carbon nanotube. The contents of (B) and (C) are described in refs. 49, 56, 57 and they are redrawn here.
