Optimization of Metal-Based Nanoparticle Composite Formulations and Their Application in Wound Dressings.

Metal-based nanoparticles (MNPs) have great potential for applications in wound healing and tissue engineering, and due to their unique structures, high bioactivities, and excellent designability characteristics, an increasing number of studies have been devoted to modifying these species to generate novel composites with desirable optical, electrical, and magnetic properties. However, few systematic and detailed reviews have been performed relating to the modification approaches available for MNPs and their resulting composites. In this review, a comprehensive summary is performed regarding the optimized modification formulations of MNPs for application in wound dressings, and the techniques used to prepare composite wound dressings are discussed.

Design Strategies and Application Potential of Multifunctional Hydrogels for Promoting Angiogenesis.

Hydrogels can be rationally designed as multifunctional platforms with structures and functions for various biomedical applications. Because of their excellent biochemical and mechanical properties, hydrogels have shown great potential for promoting angiogenesis, and an increasing amount of research has been devoted to designing and developing new hydrogels. However, a systematic and detailed review of hydrogels that promote angiogenesis is lacking.
