Abstract

The control of cancer cell adhesion behavior on certain surfaces has been widely studied in recent years to enhance cell adhesion, which is required for bio-sensing, implant biomaterials, or to prevent infections from bacteria or germs. In addition, it helps to preserve the original functions of medical devices such as implants, catheters, injection syringes, and vascular stents. In this study, we explored the behavior of mouse liver cancer cells on nanostructured surfaces in extreme wetting conditions of a superhydrophobic or superhydrophilic nature. Oxygen plasma treatment of polymeric surfaces induced the formation of nanostructures such as bumps or hairs with various aspect ratios, which is defined as the height to diameter ratio. A superhydrophobic surface with a contact angle (CA) of 161.1
