You and your dentist have a lot of tools and techniques for stopping cavities, but detecting the specific chemical conditions that can lead to cavities and then preventing them from ever getting started is much harder. Now, in a new study, ºÚÁϳԹÏÍø researchers have shown that a dental tool they created can measure the acidity built up by the bacteria in plaque that leads to cavities. The O-pH system is a prototype optical device that emits an LED…
A unique application of a medical camera developed by a ºÚÁϳԹÏÍø mechanical engineer could one day help physicians know who is at risk for stroke or heart attack by providing a better view of potential problem areas.
ºÚÁϳԹÏÍø scientists and engineers are developing a low-cost device that could help pathologists diagnose pancreatic cancer earlier and faster. The prototype can perform the basic steps for processing a biopsy, relying on fluid transport instead of human hands to process the tissue.
