An “on-off-on” type photoelectrochemical aptasensor for ultrasensitive detecting prostate-specific antigen based on resonance energy transfer

An “on-off-on” type photoelectrochemical (PEC) aptamer sensor for prostate-specific antigen (PSA) detection is constructed based on nanocomposite materials obtained from CdS functionalized titanium dioxide (CdS/TiO2 NPs). Firstly, due to high photocurrent signal of the CdS/TiO2 NPs, it can achieve t...
