Raw data: Neutral-pH Electropolymerization of Aniline on Hierarchically Porous Laser-Induced Graphene Electrodes for Dual Biosensing part 2

Physicochemical dataset including SEM imaging, Raman spectroscopy, FTIR, and XPS analyses of bare LIG and PANI-LIG electrodes prepared under acidic and neutral conditions. Covers morphology, structural disorder, chemical composition, doping state, film thickness, and surface functional groups related to electropolymerization environment.
