Journal ArticleDOI
Antigen down format photoelectrochemical analysis supported by fullerene functionalized Sn3O4.
TL;DR: A smart competitive-type photoelectrochemical (PEC) sensor based on an antigen-down (Ag-down) format for procalcitonin (PCT) detection is proposed, which exhibits excellent sensitivity and great stability.
Journal ArticleDOI
MoSe2/CdSe Heterojunction Destruction by Cation Exchange for Photoelectrochemical Immunoassays with a Controlled-Release Strategy.
TL;DR: In this article, a split-type immunoassay strategy instigated by cation exchange and changing the capacity of an electron donor in an electrolyte solution is optimized, namely, for differentiating the biological-specific binding assay and photoelectrochemical (PEC) analysis.
Journal ArticleDOI
THCH as electron donor in controlled-release system for procalcitonin analysis based on Bi2Sn2O7 photoanode
Dongquan Leng,Jingshuai Li,Rui Xu,Lei Liu,Xuejing Liu,Dawei Fan,Huan Wang,Qin Wei,Huangxian Ju,Huangxian Ju +9 more
TL;DR: A split-type photoelectrochemical (PEC) sensor for procalcitonin (PCT) detection was successfully prepared in this paper, which separated the two processes of antigen-antibody specific recognition and photoelectric conversion.
Journal ArticleDOI
Split-Type Photoelectrochemical/Visual Sensing Platform Based on SnO2/MgIn2S4/Zn0.1Cd0.9S Composites and Au@Fe3O4 Nanoparticles for Ultrasensitive Detection of Neuron Specific Enolase.
Nuo Zhang,Dongquan Leng,Yaoguang Wang,Zhuangzhuang Ru,Guanhui Zhao,Yueyun Li,Dapeng Zhang,Qin Wei +7 more
TL;DR: In this article , a dual mode detection system of split-type photoelectrochemical (PEC) and visual immunoassay was developed to detect neuron specific enolase (NSE), which achieved simultaneous and reliable NSE detection due to the completely different signal readouts and transduction mechanism.
Journal ArticleDOI
Rationally engineered high-performance BiVO4/Ag3VO4/SnS2 photoelectrodes for ultrasensitive immunosensing of CYFRA21-1 based on HRP-tyramine-triggered insoluble precipitates.
Dongquan Leng,Rui Xu,Lei Liu,Huan Wang,Jingshuai Li,Xiang Ren,Qin Wei,Huangxian Ju,Huangxian Ju +8 more
TL;DR: In this article, a photoelectrochemical (PEC) biosensor capable of detecting cytokeratin 19 fragment 21-1 (CYFRA21-1) was optimized by taking advantage of the powerful conjugate repeats of horseradish peroxidase and tyramine (HRP-tyramine)-triggered enzymatic biocatalytic precipitation (BCP) on high-performance BiVO4/Ag3 VO4/SnS2 photo electrodes.
