Asymmetric Janus Nanofibrous Agar-Based Wound Dressing Infused with Enhanced Antioxidant and Antibacterial Properties.

In the present study, we have developed an agar-based asymmetric Janus nanofibrous wound dressing comprising a support and an electrospun layer with antibacterial and antioxidant properties, respectively, to facilitate healing effectively. The support layer containing agar and silver nitrate was fabricated by using solvent casting for sustained release, combating the dose-dependent cytotoxicity of silver nanoparticles, where nanoparticles were synthesized using a one-pot reduction method. The electrospun layer, fabricated with a mixture of agar and polycaprolactone infused with gallic acid, was electrospun over the support layer to impart antioxidant properties.
