A target-induced displacement-assisted colorimetric aptasensor for tetracycline detection based on Co MOF@Au NPs nanozymes.
Tetracycline (TC) residues in milk present a potential risk to food safety and human health, highlighting the urgent need to develop rapid and reliable detection strategies. Herein, a target-induced displacement (TID)-based colorimetric aptasensor was assembled for the sensitive detection of TC using oxidase (OXD)-like...
