Nanofibrous scaffolds were prepared from gelatin solutions and were further cross-linked with glutaraldehyde (GA). The fiber diameter was varied from 100 to 1000 nm by controlling the applied voltage (4-15 kV) and the concentration of the gelatin solution (4-15%). The tensile moduli and the tensile strength of the non…
