| Abstract (English): |
A gold@platinum (Au@Pt) nanozyme-based test strip for the convenient and sensitive detection of hydrogen peroxide residues in foods was developed using Whatman No.1 filter paper as the carrier, Au@Pt nanozyme as the catalyst, 3,3’,5,5’-tetramethylbenzidine as the color developer, and acetic acid-sodium acetate solution at pH 4.6 as the buffer system. The optimized test strip soaking time was 10 s. The test paper could detect hydrogen peroxide in samples within 3 min with a minimum detection limit of 0.34 mg/kg and a good linearity (R²= 0.9931). The test paper is easy to make, highly accurate, stable and simple to operate, and can be used in the real-time on-site detection of food products in various distribution channels.
