| Summary: | Oxidation is a common physical treatment used to render the surface of polystyrene suitable
for cell adhesion and spreading. In this work, the effects of oxidation of polystyrene (PS) microspheres
by three different treatments; oxidation by ozone aeration only, UV irradiation only or by the
combination of both (UVO3), by using a self-fabricated UVO3 system were investigated. Results
expressed in carboxylic acid (COOH) concentrations on the surface of microspheres revealed that, the
treatment by UVO3 yielded the highest concentration. Presence of atomic oxygen species in UVO3
treatment has contributed to higher COOH concentration. |
