AuNPs monolayer doping

Poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT?:?PSS) film

on interdigitated electrode had been fabricated into AuNPs/PEDOT?:?PSS

Janus film sensor to detect hydrogen sulfide (H2S). The results show that the Janus film sensors have a wide measurement range of H2S

concentration. The sensitivity of PEDOT?:?PSS/AuNPs sensor grows up

with the thickness of Janus film increases. The resistance response of

AuNPs Janus film was affected little by the rough surface states of

PEDOT?:?PSS film. In addition, the PEDOT?:?PSS/AuNPs film sensor had

been used again to detect H2S. This work presents a platform to inspire a novel high sensitive chemiresistive sensor via nanoparticles monolayer.
