Special Issue Information

Dear Colleagues,

Surface modification for the development of advanced materials for biomedical applications holds significant importance within the field of materials science, and it plays an important role in enhancing the performance, biocompatibility, and functionality of materials used in various medical applications. Tailoring materials for biomedical applications by surface modification involves altering the outer layer of materials to enhance their performance, biocompatibility, and interaction with biological systems. Furthermore, designing coatings with suitable surface properties for biomedical application is a multidisciplinary area of study that aims to combine principles from various fields such as materials science, chemistry, biology, and engineering. It endeavours to develop creative solutions for medical challenges through the exploration of cutting-edge techniques and materials, with the goal of improving the performance and biocompatibility of advanced materials and coatings in diverse biomedical applications. This Special Issue is open to all fields of expertise that can contribute original research and comprehensive reviews that provide relevant information about surface modification for the development of advanced materials and coatings for biomedical applications. The research interest of this special issue will be oriented towards the surface modification as well as fundamental and functional properties of surfaces and interfaces, designing or refining processes for coating deposition and modification for obtaining advanced materials for biomedical applications. Moreover, the special issue will welcome topics regarding the development of advanced materials by surface modifications as well as the development of modification of thin films with suitable surface properties for biomedical applications.

The increasidng demand for implants due to the aging populations highlights the necessity for applying highly functional coatings on the surface of implants. This study investigates the implications of applying a chitosan/polylysine composite coating on anodized titanium surfaces, aiming for improved biocompatibility, bioactivity, and anti-bacterial properties. Titanium substrates were anodized at 40 volts for a duration of two hours, followed by dip coating with the chitosan/polylysine composite. Fourier-transform infrared (FTIR) analysis was employed to characterize the polymer structure, while field emission scanning electron microscopy (FESEM) and energy-dispersive X-ray spectroscopy (EDS) techniques were utilized to evaluate nanotube morphology and the coating structure. Results showed that samples containing 1.5% polylysine exhibited noticeable anti-bacterial properties and cell viability above fifty percent. Subsequent immersion in simulated body fluid (SBF) for a duration of two weeks revealed the formation of apatite crystals on the coated samples, indicating that the samples are bioactive. Furthermore, polylysine contributed to enhanced resistance against degradation in phosphate-buffered saline (PBS) solution. Overall, the chitosan/polylysine composite coating exhibited promising mechanical and biomedical characteristics, suggesting its potential for applications in orthopedic implants. Full article
