A piezoelectric immunosensor for chloramphenicol detection in food

Highly Sensitive Detection of Okadaic Acid in Seafood Products via the Unlabeled Piezoelectric Sensor

“…The electrode's surface was cleaned by hydrochloric acid, defatted by acetone, and then dried in air at room temperature (Karaseva and Ermolaeva 2012).…”

Switch-on fluorescence scheme for antibiotics based on a magnetic composite probe with aptamer and hemin/G-quadruplex coimmobilized nano-Pt–luminol as signal tracer

“…Many governments have made it illegal to use CAP as feed additive especially in animal food [4,5] . Therefore, a convenient and rapid method for the analysis of CAP residues in food is highly desirable.…”

“…Thus, after magnetic separation, the nanotracer can be released into the supernatant. 5 Because the hemin/G-quadruplex and PtNPs in nanotracer can catalyze luminol-H 2 O 2 system to emit fluorescence. Thus a strong "switch-on" fluorescence signal appeared.…”

A label-free photoelectrochemical aptasensor based on nitrogen-doped graphene quantum dots for chloramphenicol determination

“…The minimum required performance limit (MRPL) for CAP residues in food of animal origin was set to be 0.3 μg kg -1 by the European Union (EU) (Karaseva and Ermolaeva, 2012). To meet the demand of low detection limit in environmental waters and food, it is necessary to develop highly sensitive and selective analytical approaches to CAP determination.…”
