Yaling Liu, who has spent much of his career applying the principles of fluid mechanics and nano-engineering to biology and medicine, has been named a fellow of the American Society of Mechanical Engineers, one of the top honors in his field. ASME, a professional society founded in 1880, has more than 130,000 members in 151 countries.
Liu, an associate professor of mechanical engineering and mechanics and also of bioengineering, has developed testing and diagnostic tools that mimic the behavior of body tissue, enable the early detection of cancer and evaluate the targeted delivery of medicine at the nanoscale. He has received funding from the National Science Foundation (NSF), the National Institutes of Health (NIH), the National Institute of Biomedical Imaging and Bioengineering, and Oak Ridge Associated Universities.
In one NSF-funded project, Liu and his students have developed a cheap, portable device that detects cancerous tumors before a patient feels symptoms. The device, which Liu calls a “lab on a chip,” isolates the relative handful of tumor cells that break free from the site of a tumor and circulate among billions of normal blood cells in a single milliliter of blood. Because of its size and relatively low cost—less than $5 per unit—the device shows promise for use in developing countries.
The lab-on-a-chip device, Liu said, can identify cancer cells before a tumor grows large enough to appear on an MRI and can thus help detect cancer in its very early stages when it is easier to treat. The device can also monitor the progression of a tumor and the effectiveness of treatment. Liu and his group are working with Lehigh Valley Hospital on a clinical trial to test the device on melanoma and renal cancer patients.
