Summary: Materials for biomedical applications often need to be coated to enhance their performance, such as their biocompatibility, antibacterial, antioxidant, and anti-inflammatory properties, or to assist the regeneration process and influence cell adhesion. Chitosan, a naturally available substance, meets these criteria. Plasma treatment is an effective solution for altering the surface of synthetic polymer materials to ensure interaction with chitosan. This review focuses on plasma methods for surface modification of polymers to improve chitosan immobilization, including direct and indirect immobilization approaches.

Summary: Polydimethylsiloxane (PDMS) is a commonly used elastomeric polymer with a hydrophobic surface, hindering many applications. This study presents a novel wet-chemistry-based method to modify the PDMS surface, resulting in an amino-functionalized surface. The modified PDMS surfaces show cell-adhesive or nonthrombogenic properties through conjugation with RGD peptide, polyethylene glycol (PEG) or heparin. Additionally, antifouling surfaces are created to prevent platelet adhesion and hydrophobic recovery. These findings provide versatile surface functionalization methods for PDMS and are applicable in biomedical applications.

Summary: This study successfully created wrinkle patterns on PDMS using plasma immersion ion implantation. The results demonstrate that the wrinkles formed spontaneously without external agents, and their morphology and geometry were affected by the ion species and high voltage pulse frequency. X-ray photoelectron spectroscopy analysis revealed that ion irradiation transformed the surface of PDMS into a silica-like surface with abundant oxygen functional groups, facilitating the formation of wrinkles in PDMS.
