Scientists out there are busy working on a project that allows a simple swipe of a diagnostic biochip to be 93 percent accurate in detecting whether patients have malignant oral cancer lesions. The test involves removing cells with a brush, placing them on a chip, and inserting said chip into an analyzer that can churn out the results in 8 to 10 minutes, which is a lot faster than the current methods that could take up to a week and involve procedures that might be painful. This new system uses a disposable brush to remove a few cells from the lining of the mouth, and the cells are sent through mini-fluidic channels and come in contact with biomarkers that react with specific types of diseased cells, making them distinguishable by the way they glow under the two LEDs lights.
