Fabrication of the rose stem-like composite constructs containing spherical and branched nanoparticles. (a) Schematic illustration of fibrous composite fabrication: ZnO particles are dispersed within a PCL solution and extruded under high voltage. SEM images show the inability to confine the branched particle with consequent protrusion formation (rose stem-like structure). (b) EDAX map of dibranched and spherical ZnO particles at different concentrations (1, 3, and 5% w/v) and their distribution into the fibers. Elemental map demonstrates the distribution of Zn (blue), O (green), and C (red) in the composites.
