Abstract
Electrospinning is an
emerging technique used for fabrication of nanofibrous mats for skin tissue
engineering applications. The aim of this study centered on fabrication of
muga fibroin electrospun mats by using ionic liquid and its
characterizations. The muga fibroin extracted from cocoon of Antheraea assama
is dissolved in 1-butyl, 3-methyl imidazolium acetate (BMIMAc), a green solvent,
to prepare a dope solution for electrospinning. The molecular weight,
rheology and structural properties of dope solution are characterized. The
process parameters of electrospinning machine such as voltage and
concentration of dope solution are varied to obtain nanofibrous mats. The
nanofibrous mat having average fiber diameter of 160 nm are obtained from 10%
w/v concentration of muga fibroin in BMIMAc with an applied voltage of 20 KV.
The mechanical, structural, physical and thermal properties of muga
nanofibrous mat (MNF) are analyzed and compare with muga cast film. The
cytocompatibility test is performed using L929 fibroblast cells. It is
observed that muga nanofibrous mat support higher growth of fibroblast cells
(p < 0.05) as compared to muga cast film (MCF). Muga nanofibrous mat and
cast film are loaded with gentamycin sulphate. The release rate and
antimicrobial efficiency of gentamycin sulphate loaded muga nanofibrous mat
are found to be significantly higher (p < 0.05) as compared to muga cast film.
All these results indicate that muga nanofibrous mat would be a promising
material for skin tissue engineering.
