Split aptamer-regulated AuNF nanozymes for colorimetric and electrochemical dual-readout kanamycin biosensing.
Kanamycin (Kana) residues released into aquatic environments due to its extensive use have raised increasing concerns because of their potential risks to ecosystems and human health. In this work, we report a label-free split aptamer-modified gold nanoflower (AuNF)-based aptasensing platform with colorimetric and elect...
