Click Chemistry-Mediated Particle Counting Sensing via Cu(II)-Polyglutamic Acid Coordination Chemistry and Enzymatic Reaction

Autor: Zhilong Wang, Luyu Wei, Lingwen Zeng, Niu Feng, Jianjun Chen, Yiping Chen

Publikováno v: Analytical Chemistry. 94:5293-5300

An electrical resistance-based particle counter (ERPC) with simple operation and high resolution has proved to be a promising biosensing toolkit, whereas amplification-free ERPC biosensors are incapable of analyzing trace small molecules due to their

Optical Biosensor for Ochratoxin A Detection in Grains Using an Enzyme-Mediated Click Reaction and Polystyrene Nanoparticles

Autor: Luyu Wei, Zhilong Wang, Yiping Chen

Publikováno v: Journal of agricultural and food chemistry. 70(46)

Herein, we develop an optical biosensor for highly sensitive and facile detection of ochratoxin A (OTA) using an enzyme-mediated click reaction for signal amplification and polystyrene nanoparticles (PNPs) for signal readout. Alkaline phosphatase was

Direct Transverse Relaxation Time Biosensing Strategy for Detecting Foodborne Pathogens through Enzyme-Mediated Sol–Gel Transition of Hydrogels

Autor: Luyu Wei, Caiwei Feng, Yunlei Xianyu, Zhilong Wang, Yiping Chen

Publikováno v: Analytical Chemistry. 93:6613-6619

In this work, we develop a direct transverse relaxation time (T2) biosensing strategy and employ it for assaying foodborne pathogens relying on the alkaline phosphatase (ALP)-mediated sol-gel transition of hydrogels. ALP can catalyze the reaction to

Enzyme-modulated photothermal immunoassay of chloramphenicol residues in milk and egg using a self-calibrated thermal imager

Autor: Luyu Wei, Fu Jiao, Zhilong Wang, Long Wu, Daming Dong, Yiping Chen

Publikováno v: Food chemistry. 392

Highly sensitive and accurate detection of chloramphenicol is of paramount importance for food safety. Herein, an enzyme-modulated photothermal immunosensor that uses a self-calibrated thermal imaging system (SCTIS) as signal read-out was developed f
