Electrospun nano-fibre mats with antibacterial properties from quaternised chitosan and poly(vinyl alcohol)

Carbohydr Res. 2006 Sep 4;341(12):2098-107. doi: 10.1016/j.carres.2006.05.006. Epub 2006 Jun 5.

Abstract

Nano-fibres containing quaternised chitosan (QCh) have been successfully prepared by electrospinning of QCh solutions mixed with poly(vinyl alcohol) (PVA). The average fibre diameter is in the range of 60-200 nm. UV irradiation of the composite electrospun nano-fibrous mats containing triethylene glycol diacrylate as cross-linking agent has resulted in stabilising of the nano-fibres against disintegration in water or water vapours. Microbiological screening has demonstrated the antibacterial activity of the photo-cross-linked electrospun mats against Staphylococcus aureus and Escherichia coli. The obtained nano-fibrous electrospun mats are promising for wound-healing applications.
