Mechanistic insights into graphene quantum dots-mediated regulation of single-atom nanozyme activity for homogeneous dual-mode detection of acetamiprid.

A homogeneous colorimetric/ratiometric fluorescence biosensor was developed for acetamiprid (Ace) detection based on graphene quantum dots (GQDs)-regulated Fe/Mn-N-C single-atom nanozyme (SAzyme) activity. Aptamer-functionalized SAzymes with high peroxidase-like activity were hybridized with complementary DNA-modified...

Structure-dependent modulation of potato and corn starch gelatinization and retrogradation by Salecan

Starch retrogradation is a critical technological challenge requiring effective mitigation. This study aimed to systematically compare how Salecan, a novel food-grade linear anionic glucan, differentially modulates gelatinization and retrogradation of potato starch (PS) and corn starch (CS) based on structural differen...

Synergistic dual-recognition enabled by single-atom nanozyme and aptamer for ultrasensitive colorimetric detection of glyphosate.

While nanozyme-based inhibition strategies are attractive for on-site detection of pesticides, their sensitivity is primarily hampered by insufficient interactions at the nanozyme-pesticide interface. To address this, we developed a dual-recognition system that integrates a Fe/Cu-N-C single-atom nanozyme (SAzyme) with...
