Engineers Plays Key Role In Potential New Cancer Drug Delivery
Posted Jan 10 2011 6:38pm
Mechanical engineering professor Warren Finlay has taken on a major role in research to improve drug delivery for lung cancer patients.
Working with Faculty of Pharmacy and Pharmaceutical Sciences researcher Raimar Lobenberg and Wilson Roa at the Cross Cancer Institute, Finlay has devised a way to manufacture an inhalable powder that could effectively disperse chemotherapy drugs into a patient’s lungs.
The team encapsulated chemotherapy drugs into nanoparticles that could be inhaled by patients with lung cancer. To keep the nanoparticles apart, they first freeze the particles in tiny ice carrier particles before removing the ice to make a powder. The challenge then was to produce a powder that would not only make it into a patient’s lungs, but also disperse the drugs effectively.
