A recyclable hydrogel-based sustained release system for formaldehyde monitoring in foods

Abstract

4-amino-3-hydramidin-5-mercapto-1, 2, 4-triazacene (AHMT) is pre-doped into agarose hydrogels, and consequently, sustained hydrogel systems with the modulated release performance are constructed, contributing to the point-of-care detections of formaldehyde (FA) with...
