Targeted therapeutic delivery systems comprising specially-designed 
nanocarriers for 
intracellular therapeutic delivery, mediated by 
acoustic energy, for use either 
in vivo or 
in vitro are detailed. 
Nanocarriers comprised substantially of dendritic biopolymers and other species and compounds; are used to treat a variety of diseases in humans and other species, such as 
cancer, opthalmological, pulmonary, urinary or other pathologies. Methods for preparing the targeted therapeutic delivery systems are also embodied, which comprise 
processing a solution comprising biopolymers or other species and components, with or without targeting moieties, adding said biopolymers and other compounds to a solution containing one or more therapeutic agents, stabilizing or not stabilizing said 
nanocarriers, adding one or more contrast agents, resulting in a targeted therapeutic 
delivery system. Preferred therapeutics for use with the present invention include nucleic acids, proteins, peptides, and other therapeutic macromolecules.
