WVXU talked to a University of Cincinnati researcher who developed a noninvasive, point-of-care device for early cancer screening using a small amount of a patient’s body fluid such as saliva or blood.
Leyla Esfandiari, an assistant professor of biomedical and electrical engineering in UC's College of Engineering and Applied Science, has a patent pending on a small lab-on-a-chip device that can help doctors get accurate results without invasive biopsies.
"It's going to be faster, cheaper and more reliable," Esfandiari told WVXU. "The most important thing from the patient's point of view is that it's going to be minimally invasive. They are not going to take a tissue biopsy. They are going to get some blood or saliva."
Esfandiari and her research team in her Integrative Biosensing Laboratory at UC discovered a way to make that process faster, easier and more cost effective. Esfandiari frequently collaborates with colleagues from the UC College of Medicine and Cincinnati Children’s Hospital Medical Center. Conversations with those in the medical profession led her to explore a better way to isolate exosomes from the body fluids utilizing a novel label-free electrokinetic device.
Exosomes, or cell-secreted nanoscale extracellular vesicles, contain important gene regulatory contents and are highly abundant in all body fluids. They carry with them RNA and protein markers that indicate cancer and other diseases. While it’s easy to collect the body fluids, it’s challenging to extract exosomes from the fluid to identify the biomarkers.
