Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>Ultraviolet–ozone (UVO) is used for the cleaning of labware from organic contamination and includes sterilization, surface roughening, and activation. A range of polymers has been treated without major effects on surface topography and surface chemistry. Even for those, which are subject to physical and chemical aging, a trade‐off between damages and surface cleaning was often found. This communication presents a comprehensive overview on how to UVO‐treat selected polymers known from applications in biology and medicine, in particular microcantilevers used for biosensing. The study provides well‐defined thresholds below which degradation and surface damages are avoided. The impact of UVO treatments on the surface and bulk properties of the injection‐molded polymers was examined by means of differential scanning calorimetry and Fourier transform infrared spectroscopy measurements. © 2015 Wiley Periodicals, Inc.
