Trypsin-functionalized Ag Au nanoflowers for enhanced sensing of hydrogen sulfide in diverse foods: dual mechanisms of steric hindrance-mediated biothiols exclusion and silver-driven 30-fold cascade amplification
S detection and food-freshness evaluation across diverse samples. This work not only presents a novel and highly stable method for synthesising Try-AgAuNFs, but also reveals that surface-bound protein ligands can enhance probe selectivity through steric hindrance control.
