Nanotechnology

Nanotech-based sensor developed to measure microRNAs in blood, speed cancer detection.

"In a study published in the Nov. issue of ACS Nano, a peer-reviewed journal of the American Chemical Society focusing on nanoscience and nanotechnology research, the IUPUI researchers describe their design of the novel, low-cost, nanotechnology-enabled reusable sensor. They also report on the promising results of tests of the sensor's ability to identify pancreatic cancer or indicate the existence of a benign condition by quantifying changes in levels of microRNA signatures linked to pancreatic cancer. MicroRNAs are small molecules of RNA that regulate how larger RNA molecules lead to protein expression. As such, microRNAs are very important in biology and disease states."

"We have designed an ultrasensitive technique so that we can see minute changes in microRNA concentrations in a patient's blood and confirm the presence of pancreatic cancer." Sardar is an assistant professor of chemistry and chemical biology in the School of Science at IUPUI and leads an interdisciplinary research program focusing on the intersection of analytical chemistry and the nanoscience of metallic nanoparticles.”
