A Label-Free Aptasensor for Ochratoxin a Detection Based on the Structure Switch of Aptamer
A label-free sensing platform is developed based on switching the structure of aptamer for highly sensitive and selective fluorescence detection of ochratoxin A (OTA). OTA induces the structure of aptamer, transforms into G-quadruplex and produces strong fluorescence in the presence of zinc(II)-prot...
