An inner filter effect-based upconversion fluorescence sensor using TPPS-Co2+ complexes for rapid detection of roxithromycin in food.

An inner filter effect (IFE)-based upconversion fluorescence nanosensor was developed for the sensitive detection of roxithromycin (ROX) residues in food. Core-shell NaYF4,Er@NaYF4 upconversion nanoparticles were used as the fluorescence donor and a tetraphenylporphyrin tetrasulfonic acid cobalt complex (TPPS-Co2+) as...

Spatially and potential-resolved anti-interference ECL biosensor for simultaneous detection of ochratoxin A and aflatoxin B1.

The simultaneous detection of multiple targets using electrochemiluminescence (ECL) is often hampered by the interference between lumiphores. To address this challenge, a spatially and potential-resolved ECL biosensor was developed for the detection of ochratoxin A (OTA) and aflatoxin B1 (AFB1). Specially, graphitic ca...
