Abstract—The effect of XeCl laser irradiation on biocompatibility of polyethersulfone (PES) film surface was
investigated. For this purpose, the surface of PES film was irradiated with different number of pulses at different
fluences. The treated surfaces were characterized by attenuated total reflectance Fourier transform infrared
spectroscopy (ATR-FTIR), scanning electron microscopy (SEM), atomic force microscopy (AFM) and contact
angle measurements. The platelet adhesion and cell culture measurements were done on the treated surface for
investigation of the biocompatibility. It was shown that, irradiation of surface with 500pulses at a fluence of 25
mJ/cm² is the most optimal condition for improving the platelet adhesion on the PES surface with a XeCl laser.
