ABSTRACT The effect of Argon ion irradiation to the surface properties of poly(lactic-co-glycolic) acid (PLGA) was studied. A beam of 170 keV Argon ions was implanted at different fluencies (1 × 10 12 , 1 × 10 13 , 1 × 10 14 , and 1 × 10 15 ions/cm 2 ). X-ray photoelectron spectroscopy (XPS) was used to analyze the evolution of the bonding microstructure of PLGA due to irradiatio...
