12/21/12Siyang Zheng, assistant professor of bioengineering, has been awarded a $720,000 grant from the American Cancer Society.
The four-year grant will allow Zheng to investigate how metastatic cancer cells release circulating tumor cells (CTCs) that travel through the blood and invade different parts of the body, a process that accounts for more than 90 percent of cancer related deaths, according to the American Cancer Society.
Zheng's laboratory has taken a novel approach to obtaining CTCs, a challenging process, using an array of flexible microsprings to improve the filtration process. This could allow testing of drugs to measure their benefit without exposing a patient to the unnecessary cost or toxic effects of chemotherapy.
