A review on the synthesis and development of alginate hydrogels for wound therapy

Abstract

The convenient and low-cost dressing can reduce the difficulty of wound treatment. Alginate gel dressing has the advantages of low prices and safety in use, which it has obvious potential...

Screening and investigation of a short antimicrobial peptide: AVGAV

“…Considering the peptide instability, when combined with wound treatment materials (such as a hydrogel), it may have a better effect. 34 The therapeutic effect of antimicrobial peptides in organisms still needs to be verified. AVGAV promotes the healing of superficial wounds and inhibits bacterial infections at the wound site (Fig.…”

Preparation and Properties of Self-Assembling Polypeptide Hydrogels and Their Application in Biomedicine

“…In the process of treating wounds, wound healing, the most challenging problem is to prevent infections caused by microbial invasion, especially in burns and chronic wounds, which lead to slow wound healing and increased. − To address such problems, peptide-based antimicrobial materials have been developed into effective weapons to fight off bacterial infections. , In addition, the resistance of bacteria to antimicrobial peptides (AMPs) is low or almost nonexistent, which favors aseptic treatment of wound . Currently, self-assembling materials based on antimicrobial peptides primarily utilize cationic properties, assembly structures, or the ability to carry antimicrobial agents to kill bacteria to prevent infections caused by bacteria and treat wounds. , Cationic self-assembling polypeptides rich in lysine and arginine have a polycationic surface and have antibacterial activity against broad-spectrum Gram-positive and Gram-negative .…”

An iron phosphate hydroxide hydrate electrocatalyst: synergistic effects of Fe2+ and Fe3+ for enhanced hydrogen evolution reaction stability

“…7,8 In order to reduce the excess potential needed to drive the hydrogen evolution reaction, active catalysts are required. 9,10 Due to the instability and high cost of noble metals, alternative materials are under research to produce hydrogen based on 3d-orbital transition metal oxides, [11][12][13] hydroxides, [14][15][16] suldes, [17][18][19][20] selenides [21][22][23][24] and phosphides/phosphates (TMPs). [25][26][27][28] Among them, TMPs offer a number of active sites for catalytic processes and have many exposed crystalline surfaces despite lacking a layered structure.…”
