Abstract

•Pt single-atom nanozyme (SA-Pt/CN) with oxidase-like activity is prepared.•Catalytic mechanism is discussed in detail.•SA-Pt/CN can distinguish hydroquinone from other phenolics.•Colorimetric α-glucosidase assay is designed using α-Arbutin as substrate.•Colorimetric “NAND” logic gate is constructed.
