Nanoparticles have been shown to be effective Drug Delivery Systems because of their biocompatibility and biodegradability. Nanoparticles act as potential carries for several classes of drugs such as anticancer agents, antihypertensive agents, immunomodulators, and hormones; and macromolecules such as nucleic acids, proteins, peptides, and antibodies.
Adaptive Focused AcousticsTM (AFA) technology can be used in the emulsification steps of PLGA nanoparticle formation, to achieve monodisperse particle size distributions as small as 80nm. Additionally, the intense yet highly controllable mechanical energy of AFA allows the use of mild solvents, such as triacetin, in AFA-Nanoparticle formation. Combined with inherent low temperature processing, AFA-Nanoparticles are formed using temperature and solvent sensitive materials that would degrade with traditional processing methods.
