FIG. 1.

Representative images of the scaffolds. (A) Gross image of electro spun poly(lactide-glycolide-caprolactone) (PLGC). (B) Environmental scanning electron microscopy (ESEM) image of bare PLGC. (C) Bright field micrographs of bare PLGC. (D) Bright field micrographs of hybrid PLGC showing fibrin network. (E) Merged attenuated total reflectance-infrared spectroscopy of (a), bare PLGC scaffold, (b) fibrin composite matrix sheet, and (c) hybrid PLGC scaffold. Spectral recording of hybrid scaffold shows characteristic peaks of O-H stretching, amide 1 band and amide 2 band at 3275 cm⁻¹, 1627 cm⁻¹, and 1540cm⁻¹, respectively which is seen in the spectrum of fibrin composite. These peaks are absent in the spectrum of bare PLGC.
