Abstract
An effective photoelectrochemical (PEC) detection methodology was established and used to determine l-cysteine based on the ultrathin polythiophene layer sensitized anatase TiO2 on F-doped tin oxide substrates (PTh/TiO2/FTO). The PTh/TiO2 core-shell composites were synthesized by in situ polymerization of thiophene on TiO2 nanoparticle surfaces, resulting in a 1-nm-thick \PTh\ layer decorated TiO2. The ultrathin layer could improve the electronic conductivity and enhance the light absorption, indicating that the PTh/TiO2/FTO electrode might strengthen a weak electrical signal response in detecting the low concentration of l-cysteine. Under Xe light of 25 mW cm?2, the \PEC\ detection limit of l-cysteine was 12.8 ?M from the transient photocurrent response method (linear range: 0.1
