Abstract
The objective of this work was to fabricate electrospun hybrid nanofibers based on cellulose acetate (CA) and poly (vinyl alcohol) (PVA) containing tetracycline hydrochloride (TC) and phenytoin sodium (PHT-Na), respectively. The performance evaluation of the samples was investigated in terms of morphology, drug release, cell cytotoxicity, adhesion, antibacterial property, as well as wettability. The results showed that the CA/PVA hybrid nanofibers have a uniform shape and a narrow diameter distribution (160–180 nm). The release trend of TC from CA significantly decreased in hybrid nanofibers owing to the gelation of PVA in an aqueous solution, and the release mechanism followed the Higuchi model. Besides the improvement in cell growth and the viability of CA/PVA hybrid samples, their antibacterial activity against E. coli and S. aureus stood at ~89% and ~98%, respectively. Furthermore, the obtained result from water contact angle showed a good hydrophilic property for the samples with value of 45° which made them promising materials used in biomedical applications potentially.
