You-Yeon Won explains the difference between Fick's Law and a modified version he developed that could help in cancer drug delivery to tumor cells.
Delivering drugs to cancer patients may one day be improved because of a new theory by a Purdue University professor.
Developed by You-Yeon Won, associate professor of chemical engineering, the "pH phoresis" concept involves using nanoparticles to deliver anticancer drugs to tumor cells.
The theory is centered around how nanoparticles - made of weak polybases - behave when they are exposed to changes in pH environments. Solid tumors have significantly lower pH levels - that is, they are acidic - relative to normal tissue, Won said. ...
