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

Aerodynamic characterization of PRINT aerosols. (a) SEM micrographs and aerodynamic performance of 1.5 μm, 3 μm, and 6 μm particles by APS. PRINT affords precise control over particle geometric size and aerodynamic size. (b) SEMs and aerodynamic distributions of jet-milled itraconazole aerosols compared to 1 μm PRINT cylinder particles made out of itraconazole. PRINT-itraconazole particles result in a narrower size distribution and higher available respirable fraction.
