Impedance and cyclic voltammetry studies of GPLA electrodes after laser ablation

The 3D printed GPLA electrodes present a brand new opportunity for electrode material for electrochemical biosensors. In order for the electrodes to be considered viable for electroanalysis studies, the pretreatment procedure must be applied in order to etch PLA matrix and reveal graphene filler. The following dataset presents an approach towards such a pre-treatment procedure through laser ablation. The dataset contains electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) studies of laser ablation treatment on graphene-doped polylactide (GPLA) 3D printed electrodes. The laser ablation process was carried out under various laser wavelengths, energy densities and exposure time, each of these provided in individual file titles. The file titles were given according to the following style:date_GPLA_AL_laser.wavelength_spot.size_energy.density_time_electrochemical.study
