A miniaturized confocal microscope that uses a laser to illuminate parts of a sample and can produce full three-dimensional images could help dentists identify early-stage oral cancer, University of Texas at Austin bioengineers report in the Journal of Micromechanics and Microengineering. The device also would be useful in oral cancer surgery, researchers said. "Once a patient is diagnosed with oral cancer, surgeons will remove soft tissue and even some of the bone. We want to make sure they can create the correct surgical margins, which is very important for the quality of life for the patient," said Ting Shen, CEO of NanoLite Systems, which is working with the researchers to bring the device to market.
