Electrospun Nanofibers of Curdlan (beta-1,3 Glucan) Blend as a Potential Skin Scaffold Material
2019/11/27 21:40:30 admin
Curdlan (-1,3 glucan) (7 wt%) with polyvinyl alcohol (PVA) (10 wt%) is blended at 1:2 weight ratio and electrospun to get nanofibers and is crosslinked with glutaraldehyde vapor to make it insoluble in water. It has a fiber diameter of less than 100 nm and is hydrophilic (contact angle = 35 degrees). It is biodegradable (10% in 14 d) and also has a good swelling behavior (approximate to 170%). More than 100% of L6 cells are viable on this scaffold after 3 d. The scanning electron microscope images also reveal that cells are able to attach and spread in the nanofibrous scaffolds. In vitro scratch assay indicates that the wound closure rate of curdlan/PVA scaffold is better than PVA scaffold probably due to the immunomodulatory properties of the biopolymer. Thus our results indicate that curdlan/PVA scaffold can be an ideal material for wound healing applications.
