Various electrospun nanofibers made of PCL, PCL/hydroxyapatite, polystyrene, and SF were surface-modified by air or argon plasma, resulting in an improved cell adhesion and proliferation (Venugopal et al. 2008 Prabhakaran et al. 2008 Yang et al. 2008). PCL nanofibrous scaffolds were surface-modified by a simple plasma treatment process to enhance the Schwann cell adhesion, proliferation, and interactions with the nanofibers necessary for nerve tissue formation (Prabhakaran et al. 2008). The results showed that plasma-treated PCL nanofibrous scaffolds are a cost-effective material compared with PCL/collagen scaffolds and can potentially serve as an ideal tissue-engineered scaffold, especially for peripheral nerve regeneration.

An atmospheric plasma treatment was successfully applied to AgNOs/PAN solution in DMF to reduce AgNOs salt into Ag NPs within 5 min without the addition of adverse chemicals. Antibacterial electrospun Ag/PAN nanofibers were obtained and morphologically characterized [79].
