Zno nanowires application in controlling the wettability for biomedical uses — •Amitender Singh and Saravjeet Singh — Deenbandhu Chhotu Ram University of Science and Technology Murthal, Sonipat-131039, India

Hydrophobic materials are widely used for different biological applications and nanostructures are mainly used for preparation of hydrophobic surfaces. Mainly used materials and polymers for these studies are silicone, polydimethylsiloxane (PDMS) and poly (methyl methacrylate) (PMMA) etc. To achieve this hydrophobicity, various attempts have been made recently to improve the surface properties by various chemical and physical methods. The host-material interactions take place through the surface of the material. So, the material*s biocompatibility is mainly related to its surface properties more as compared to its bulk properties. Further, Wang et al. showed that ZnO nanowires are completely bio-safe and biocompatibility when used in various concentrations below 100μg/ml. This study is aimed to develop facile method to prepare hydrophobic coating on various substrates for different biomedical applications. Here, we report the variations in contact angle on various substrates like; glass, quartz, Si and PDMS where CA measurements were done before and after ZnO nanowires coating. A drastic change in CA was found after ZnO nanowires coating on various substrates. It was found that the surface wetting properties can be tuned further for various biomedical applications like wound dressing, surgical tools and bio implants.
