The present study focuses on the synthesis and evaluation of neomycin-loaded hydrogels as potential substrate for wound healing application. Herein, genipin crosslinked gelatin interpenetrated diosgenin-modified nanocellulose (DGN-NC) hydrogels were synthesized. The hydrogels' chemical structures as well as surface morphology, mechanical property, and thermal behavior were characterized. Swelling analysis and gelation kinetics of the hydrogels were studied and the results obtained showed good swelling capacity as well as high gel yield. In addition, the prepared loaded hydrogels were evaluated for antibacterial activity against human pathogenic E. coli and S. aureus bacteria with inhibition capacity determined in the range of 50-88%. In vitro cytocompatibility and drug release studies were also explored under simulated physiological conditions achieving high cell viability and release percentage >80% and >90% after 24 h, respectively. In effect, the design hydrogels in the present study possess adequate incorporated antibacterial properties with significant potentials towards wound dressing and healing applications.

Biocompatible and degradable hydrogels are extensively utilized for the delivery and controlled release of bioactive agents. Chitosan/squid ring teeth protein (SRT) hydrogels (CH/SRTs) cross-linked by genipin were fabricated, and their gel properties and structural characteristics were analyzed across varying SRT contents. Additionally, the curcumin-release behavior of curcumin-loaded CH/SRTs (Cur-CH/SRTs) was evaluated.

Electrospun nanofiber scaffolds have become vital in biomedical applications due to their high surface area and tunable properties. Chitosan (CS) is widely used, but its rapid degradation limits its effectiveness. This study addresses this limitation by blending CS with polycaprolactone (PCL) and applying genipin cross-linking to enhance its stability and mechanical properties.

Approaches to regenerate vocal fold in glottic insufficiency remains to be a focus for exploration. This is attributed to the applications of cells or biological molecules alone result in fast degradation and inadequate for regeneration. Development of an injectable hydrogel for glottic insufficiency is challenging, as it needs to be non-cytotoxic, elastic yet possess good strength and easy to fabricate.

As a natural cationic polymer material, the application of chitosan hydrogel for bone tissue engineering has been greatly limited due to its poor mechanical strength. Enzymatic mineralization has drawn increased attention to effectively improve the mechanical properties of hydrogels. In this study, carboxymethyl chitosan (CMCS) hydrogels cross-linked with different concentrations of genipin (2.

With increasing clinical demands for painless and easy administration of medications, such as for hair loss, microneedles (MNs) have been widely exploited for facilitating drug permeation in a minimally invasive manner. However, precise dose control and long-term drug delivery without the infection risk through punctured holes have remained unresolved. Herein, we developed swellable microneedles (MNs) with an air-pocket structure, enabling shear-induced implantation inside the skin.
