Summary:Title screen
In the present study, we report a simple and efficient method of gelatin immobilization on the surface of PLA electrospun fibers using pre-treatment with a mixture of toluene and ethanol allowing to form swelled surface layer followed by gelatin adsorption from its solution in PBS. Our results demonstrate that gelatin immobilization leads to a decrease in the water contact angle from 120° to 0°, enhances scaffold strength up to 50%, and doubles the number of adhered cells and their average area. We observed that the maximum amount of gelatin (0.07?±?0.01?mg per cm3 of the scaffold) was immobilized during the first five minutes of exposure to the gelatin solution. Modified scaffolds demonstrated increased strength.
