Summary
Chitosan is an obvious candidate for infection-resistant biomaterials thanks to its intrinsic antibacterial activity, and electrospinning processes it with minimal disturbance to its physicochemical properties. The catch is that fabrication parameters and post-processing can significantly alter that biological activity, so they must be tuned rather than assumed. This study prepares chitosan nanofibrous membranes using trifluoroacetic acid and systematically examines how electrospinning parameters and the post-treatment route affect antibacterial and antifungal performance - the practical question for anyone moving chitosan fibres from laboratory to application.
