Special Issue Information

Dear Colleagues,

Biomass-based composite hydrogels have developed rapidly in the past decade, promising new materials for various fields. Compared with the most common hydrogels, biomass-based composite hydrogels can own specific advantages such as being bio-degradable and having a highly increased specific surface area and highly enhanced mechanical strength, owing to the composited biomasses including diverse bio-macromolecules and natural biomass-based nano/microstructures. Therefore, biomass-based composite hydrogels can provide various excellent functions, which have been utilized in bio-mimetic soft mini-actuators, biomedical/wearable sensors, heavy metal detections/adsorptions for environmental protection, anti-bacteria/anti-adhesion, and so on. However, research of biomass-based functional gels is in its infancy; it is still a great challenge for scientists to expand the depth and breadth of this research, so as to further extend the types of biomass materials for hydrogels and greatly extend the functions/applications in the future.

Therefore, this Special Issue on “Recent Advances in Biomass-Based Functional Gels” will focus on research referring to the subject of biomass-based functional gels (hydrogels, aerogels, organic gels, ionic liquid gels and their composites). We are pleased to invite you to contribute your recent work for this Special Issue. Submitted works may be recent research articles, reviews or prospective studies on the subject of bioinspired polymeric gels, including but not limited to the following topics: bio-mimetic soft mini-actuators, biomedical/wearable sensors, heavy metal detection/adsorption for environmental protection, anti-bacteria/anti-adhesion, self-healing, bio-degradation and mechanical strength enhancement.

The management of wound healing represents a significant clinical challenge due to the complicated processes involved. Chitosan has remarkable properties that effectively prevent certain microorganisms from entering the body and positively influence both red blood cell aggregation and platelet adhesion and aggregation in the bloodstream, resulting in a favorable hemostatic outcome. In recent years, chitosan-based hydrogels have been widely used as wound dressings due to their biodegradability, biocompatibility, safety, non-toxicity, bioadhesiveness, and soft texture resembling the extracellular matrix. This article first summarizes an overview of the main chemical modifications of chitosan for wound dressings and then reviews the desired properties of chitosan-based hydrogel dressings. The applications of chitosan-based hydrogels in wound healing, including burn wounds, surgical wounds, infected wounds, and diabetic wounds are then discussed. Finally, future prospects for chitosan-based hydrogels as wound dressings are discussed. It is anticipated that this review will form a basis for the development of a range of chitosan-based hydrogel dressings for clinical treatment. Full article
