Abstract

Background: laser irradiation is a promising method for modifying and nano-structuring of the polymer surfaces. These nanostructures induced by laser irradiation can improve biocompatibility of polymers, significantly.Material and Methods: In this study, surface of polystyrene (PS) films were treated using ArF Excimer laser (wavelength=193 nm) at different number of pulses. The changes were characterized by atomic force microscopy (AFM), attenuated total reflectance Fourier transform infrared (ATR-FTIR), scanning electron microscopy (SEM) and contact angle measurements. L929 cell culture was used to investigate the biocompatibility of treated laser PS.Results: The data from ATR-FTIR spectra showed the induction process of oxygen-based functional group into laser treated PS surfaces. AFM and SEM observations demonstrated that a specific nanostructure was created on the laser-treated PS surface. Contact angle measurement indicated that water drop contact angle with one pulse laser-treated PS surface decreased and then gradually increased because of further laser pulses. The data from in vitro assays showed the significant cell attachment and growth onto laser treated samples.
