UV Laser-Induced Carbon Microelectrode Arrays for Neuronal Recordings.

ABSTRACT: Bioelectronic devices for in vitro and in vivo studies benefit from polymeric materials as substrates and insulations due to their flexible nature. Laser-induced carbon formation has emerged as a rapid and versatile technique to fabricate conductive carbon-based structures from insulating polymer films. Here, the development of electrodes fabricated via ultraviolet (UV) laser-induced carbonization of chlorinated poly-p-xylylene (parylene-C) insulation areas is reported. The parylene-derived carbon is directly fabricated over the thin metallization layer, thus opening the desired electrode areas in a one-step process. The optimal laser parameters for electrode performance are investigated, and the stability of the electrodes is tested under 10 000 voltage-controlled stimulation pulses. In v
