Sensitive colorimetric detection of ochratoxin A by a dual-functional Au/Fe(3)O(4) nanohybrid-based aptasensor

A novel colorimetric aptasensor based on a Au/Fe(3)O(4) nanohybrid was developed to detect ochratoxin A (OTA). The aptasensor is composed of a free OTA aptamer, a Au/Fe(3)O(4) nanohybrid coated with biotinylated complementary DNA of the OTA aptamer (biotin-cDNA-Au/Fe(3)O(4)), and free alkaline-phosp...
