Special Issue Information

Dear Colleagues,

Biomaterials play crucial roles in various fields, including medicine, tissue engineering, and drug delivery, due to their ability to interact with biological systems. The modification, characterization, and application of biomaterials are key areas of research for improving their performances and expanding their range of uses.

The modification of biomaterials involves tailoring their properties to meet specific requirements for different applications. This can include making surface modifications to enhance biocompatibility, the incorporation of bioactive molecules to promote cell adhesion or changes in mechanical properties for tissue engineering applications.

The characterization of biomaterials is essential to understand their structures, properties, and interactions with biological systems. Techniques such as spectroscopy, microscopy, mechanical testing, and degradation studies are typically used to analyze the chemical compositions, morphologies, mechanical strengths, degradation kinetics, and biological responses of biomaterials.

The applications of biomaterials are diverse and include medical implants, drug delivery systems, scaffolds for tissue regeneration, and diagnostic tools. Biomaterials are used in orthopedic implants, dental materials, cardiovascular devices, and neural interfaces, among others, to improve patient outcomes and quality of life.

Overall, the field of biomaterials continues to evolve through advancements in their modification, characterization, and innovative application, enabling progress in healthcare, biotechnology, and materials science.

This Special Issue will cover current research progress on developing novel biomaterials with enhanced properties, improving characterization techniques to better understand their behavior in complex environments, and exploring new applications in emerging fields such as bioelectronics and personalized medicine.

Biopolymers represent a significant class of materials with potential applications in skin care due to their beneficial properties. Resveratrol is a natural substance that exhibits a range of biological activities, including the scavenging of free radicals and anti-inflammatory and anti-aging effects. In this study, chitosan/konjac glucomannan resveratrol-enriched thin films were prepared. The enrichment of biomaterials with active ingredients is a common practice, as it allows the desired properties to be obtained in the final product. To characterize the films, several analyses were performed, including infrared spectroscopy, imaging of the samples by SEM and AFM techniques, swelling analysis in pH 5.5 and 7.4, mechanical and antioxidant assays, contact angle measurements, and determination of the resveratrol release profile under the skin mimicking conditions. Resveratrol incorporation into the matrices resulted in modifications to the chemical structure and film morphology. The mechanical characteristics of films with additives were found to undergo deterioration. The sample containing 10% of resveratrol exhibited a higher swelling degree than other films. The resveratrol-modified films demonstrated a notable antioxidant capacity, a reduced contact angle, and enhanced wettability. The resveratrol release occurred rapidly initially, with a maximum of 84% and 56% of the substance released depending on the sample type. Thus, the proposed formulations have promising properties, in particular good swelling capacity, high antioxidant potential, and improved wettability, and may serve as skin dressings after further investigation.
