This paper describes the effects of surface modification process using oxygen plasma treatment to form molybdenum (Mo) electrodes on a poly(L-lactic acid) (PLLA) substrate. The oxygen plasma treatment was capable of physical and chemical modifications as increasing surface roughness and polar groups at the surface of the PLLA substrates. These physical and chemical modifications affected to improve the adhesiveness at the Mo/PLLA interface. Laser ablation enabled selective removal of Mo thin-layer on the PLLA substrates. Bio-resorbable and absorbable materials can potentially lead to revolutionary change in implantable medical electronics.
