Porous Fe/CeO2 Nanozyme-Based Hydrogel Colorimetric Platform for on-Site Detection of Kanamycin

Abstract: Excessive use of antibiotics causes their residues in the environment and food, seriously threatening ecosystem and human health. Designing a portable and sensitive sensor for on-site analysis of antibiotics is therefore in high demand. In this study, we have developed a smartphone-capable hydrogel colorimetric platform for ultrasensitive detection of kanamycin (KAN) based on aptamer-regulated nanozyme activity. The synthesized Fe/CeO2 hexagonal bipyramidal microcrystals (Fe/CeO2 HBs) exhibited excellent perox… Show more
