AeroCore
Supporting research and product
development through inhalation
drug delivery

Core Activities
• Aerosol generation
• Characterization of aerosol particles (output/particle
size distributions)
• Exposure of rodents to aerosol particles or vapors
• Measurement of chemicals deposited in the
respiratory tract and accumulation in blood of rodents
• Gross and microscopic examinations of rodents
• Disease induction in animal models (e.g. cancer)

1. Drug solubilization through engineering solid form
(nanocaging, solid dispersion, cocrystallization, salt
formation, etc.)
2. Tablet formulation and manufacturing process
understanding and control
3. Structure-mechanical property relationship in
organic crystals and powders
CC C.C. Sun
The aqueous solubility of poorly soluble drugs is significantly improved by
nanocaging.

Kandimalla lab drug delivery
