Chitosan-poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)-AuNPs composite for acetone detection using plasmonic image sensor.

ABSTRACT: Since acetone has more medical and industrial applications, its detection plays a significant role in indirectly measuring some quantities and controlling human safety in medical and industrial areas. In this research, a surface plasmon resonance image sensor was developed based on chitosan, poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS), and gold nanoparticles for the detection of acetone. The gold nanoparticles have been fabricated using the laser ablation technique, and chitosan-PEDOT: PSS and chitosan-PEDOT: PSS-gold-nanoparticles composite were used to detect the pure acetone vapor form using a surface plasmon resonance image sensor. The response of the sensor was compared with the sensor's response when acetone was mixed with methanol and ethanol. Consequently, t
