Abstract: Compositions including a plurality of particles that may be prepared from a chitosan salt and methods for preparing the same. The plurality of particles may have an average diameter ranging from about 100 μm to about 750 μm, such as from about 150 μm to about 500 μm; a steepness value ranging from about 30 to about 90; and an average aspect ratio greater than 0.6. The plurality of particles may be substantially spherical in shape, for example. Methods of preparation include electrospraying a chitosan salt solution through a needle.
