• This paper describes the effective fabrication of an inverse opal (IO) structure for plasmon-induced hyperthermia applications using silver nanoparticles (AgNPs) doped in a conducting polymer of poly(3,4-ethylene dioxythiophene) (PEDOT). Indium tin oxide (ITO) substrates were firstly modified electrochemically by a layer of the inverse opal structure of PEDOT (IO-PEDOT). These as-prepared electrodes were subsequently used as working electrodes for electrodepositing AgNPs. The presence of plasmonic AgNPs doped inside a polymer network caused the hybrid of IO-PEDOT and AgNPs to generate significantly more heat than thin-film PEDOT, thin-film PEDOT/AgNPs, and IO-PEDOT under 532 nm laser irradiation. This is attributed to the synergistic effect of the large active area inverse opal structure and doped AgNPs, which exhibit more thermal energy and heat faster than the individual component structures. These findings point to a wide range of potential applications for hybrid IO-PEDOT/AgNPs in hyperthermia treatment.
