Adhesive tape-based method could help screen skin cells for melanoma

from Chemical & Engineering News

Melanoma is the deadliest form of skin cancer and not something on which dermatologists like to take chances. When they see a suspicious-looking mole on the tip of a patient’s nose, they biopsy it and send it off for testing. But those biopsies come back negative at least 75% of the time—good news, but at the price of a snip and occasional scar. Now, researchers are aiming to decrease the need for biopsies by turning to a screening method that uses adhesive tape. The tape pulls off a layer of cells and then gets put through a scanning electrochemical microscope (SECM) to check for a known melanoma biomarker. more
