Schematic illustration of various electrospraying nozzles (top) and possible morphologies and structures (bottom) of particles achieved using these spraying nozzles. The configurations of the nozzle include single spraying nozzle, co-axial nozzle, tri-co-axial nozzle, multiple-channel nozzle, side-by-side nozzle, and bi-polar nozzle. By making use of these nozzles, particles obtained can be spherical, red-blood cell shaped, hollow, multicompartmental, core-shell, teardrop shaped, cup-shaped, porous, corrugated, and irregular shaped etc.
