"Diving Board" Sensors Key to DNA Detection

A tiny vibrating cantilever sensor could soon help doctors and field clinicians quickly detect harmful toxins. The list includes bacteria certain types of cancer from small samples of blood or urine. Researchers from Drexel University are in the process of refining a sensor technology, into an accurate method for quickly detecting traces of DNA in liquid samples. According to lead researcher Dr. Raj Mutharasan, a professor in Drexel’s College of Engineering, the group’s unique application of lead zirconate titanate (PZT) to current piezoelectric-excited cantilever sensor technology has allowed a way to conduct more sensitive and timely tests for DNA. This DNA test will allow for quick identification of harmful cells and bacteria.
