This study found that a chitosan-based hydrogel containing silver nanoparticles and ibuprofen demonstrated strong antibacterial activity and accelerated wound healing in vivo, suggesting its potential use in wound dressings.

This study reported that a composite hydrogel made with Chlorella-derived extracellular polysaccharide–selenium nanoparticles showed strong antibacterial and anti-inflammatory effects in vitro and significantly accelerated wound healing in vivo, offering potential for managing infected wounds and monitoring healing progression.

In this study, researchers developed a composite paste system using minoxidil-loaded nanoparticles and valproic acid, enhanced by roller-microneedles, which significantly stimulated hair regeneration and perifollicular vascularization in an androgenetic alopecia mouse model, reducing side effects compared to traditional treatments.

This study found that cefazolin-loaded silica nanoparticles embedded in polycaprolactone nanofibers successfully inhibited Staphylococcus aureus growth while maintaining stem cell viability, suggesting their potential use in wound healing.

This study reviewed chitosan composites, specifically those with silver or zinc oxide nanoparticles, highlighting their enhanced antimicrobial efficacy and potential biomedical applications despite pure chitosan's limitations such as pH sensitivity and poor solubility.
