wound healing

Modern wound care faces major challenges: both chronic and acute wounds require more than simple protection - they need targeted support of the body’s natural healing processes. Innovative delivery systems that combine bioactivity, biocompatibility and controlled release are therefore gaining increasing attention.

The efficient treatment of wounds remains a major challenge in modern medicine. Infections, in particular, are one of the main factors that can delay or even prevent healing. While traditional dressings primarily serve a protective function, the development of active, multifunctional wound dressings has increasingly come into focus.

Treating infected burn wounds - especially those involving antibiotic-resistant bacteria - remains a major challenge in modern medicine. A research team has now introduced a groundbreaking solution: a hydrogel-based microneedle system that combines so-called “high-entropy nanozymes” with chitosan.

This novel technology not only combats resistant pathogens but also actively promotes wound healing—with a special focus on chitosan’s role as a key material.

Chitosan nanofibers can be used in many different ways. In the publication presented here, electrospinning is used to produce chitosan nanofibers to improve wound healing.

Dental, bacterial diseases such as periodontitis can lead to tooth and bone loss. In the study presented here, chitosan, gelatine and Scutellariae baicalensis radix were combined to form a hydrogel to produce an anti-inflammatory implant using 3D bioprinting.

The antioxidant, bacteriostatic and antinflammatory properties of chitosan ensure that it is highly suitable for regenerative medicine applications such as wound dressings. In the presented study, a chitosan derivatized via a Schiff base is introduced to further improve these properties.

The antimicrobial effect of chitosan is well known and has already been used in dentistry to prevent caries as well as in the food packaging industry as a preservative agent.
