Microfabricated Engineered Particle Systems for Respiratory Drug Delivery and Other Pharmaceutical Applications

Figure 1

Schematic illustration of the PRINT process. (a) Features on a hard silicon master template are replicated with high fidelity (b) to obtain a soft, polymeric mold with micro- and nanocavities that can then be (c) filled with relevant particle matrix and (d) extracted out of the mold and onto a harvest array for (e) particle collection and purification.
