Synergistic enrichment and catalytic sensing platform based on ZIF-8-NH₂/dynamic Schiff base hydrogel for ultrasensitive detection of hydroquinone (opens in new tab)

IntroductionThe development of sensing interfaces that can simultaneously achieve efficient enrichment of targets and enhanced electron conduction is the key to improving the performance of phenolics detection in foodMethodsIn this paper, a novel electrochemical sensing platform consisting of an aminated zeolite imidazolium ester backbone material (ZIF-8-NH2) composited with sodium oxidized alginate (OSA)/carboxymethyl chitosan (CMCS) dynamic hydrogel (denoted as OC hydrogel) was successfully...
