Abstract

Abstract

En 中文
• Split aptamer-regulated AuNF nanozymes enable dual-readout kanamycin sensing. • DNA modification improves TMB affinity and AuNF peroxidase-like activity. • Target-induced AuNF aggregation suppresses TMB oxidation signal. • Detection limits reach 0.51 and 0.074 nM in dual readouts. • Spiked water samples gave 87.7–106.2% recovery with variation below 5%.
