Bacterial infections impede skin wound healing, and antibacterial hydrogels have garnered significant attention in the field of wound care due to their combined therapeutic effects. In this study, an intelligent, responsive AC-Gel@Cur-Au hydrogel was developed using temperature-sensitive agarose and pH-responsive chitosan as the structural framework, infused with Gel@Cur and AuNR. The AC-Gel@Cur-Au hydrogels demonstrated excellent mechanical properties, swelling capacity, tissue adhesion, and biodegradability.

The use of bioresorbable compositions has been considered a promising therapeutic approach for treating compromised bone tissues. Gellan gum (GG) is a predominant polysaccharide recognized for its exceptional biocompatibility and biodegradability, facile bio-fabrication, and customizable mechanical attributes, rendering it well-suited for developing versatile bone scaffolds. On the other hand, MXene nanosheets have been declared a representational filler to augment the osteogenic effect and amend the mechanical properties of the polymeric biomaterials.

Failures in endodontic treatments are common due to microbial resistance in the pulp canal. The study evaluated the in vitro activity of polyhexamethylene guanidine hydrochloride (PHMGH) against endodontic strains, as well as in vivo toxicity. Using minimum inhibitory concentration and minimum bactericidal concentration techniques, PHMGH was effective against all microorganisms, even at low concentrations.
