In a breakthrough, scientists have developed a toothbrush-like instrument that could detect oral cancer just in 15 minutes with a gentle touch.
A team of scientists led by researchers at the Rice University have created a nano-bio-chip that was found to be 97 per cent "sensitive" and 93 per cent specific in detecting which patients had malignant or premalignant lesions.
The minimally invasive technique would deliver results in 15 minutes instead of several days, as lab-based diagnostics do now, the researchers said.
