Abstract
This application discloses the approach of synthesizing cellulose acetate nanoparticles and rods which may have a chemically functionalized surface and an encapsulated cargo load. Functionalization and/or loading of the cargo are made through a physical mixing of the functionalizing and/or cargo components in the synthesizing bath. This can result in particles with functionalized surfaces with various functional groups, as well as active cargo load encapsulated in the particles. The encapsulated cargo includes but is not limited to biologically, chemically, and optically active substances.
