American researchers have created a sensor capable to distinguish melanoma cells from normal skin cells.
Constructed of nanoscale carbon tubes coated with DNA strands, the tiny sensor can solve a wide range of tasks, including the identification of a specific molecule smell. Unique human skin cells smells can be used to identify melanoma – the most dangerous form of skin cancer.
The authorship of the unique sensor belongs to a group of scientists from Monell center and the University of Pennsylvania.
We will remind you that melanoma is a tumor that affects skin cells which produce the dark pigment giving the skin its color.
About 75 percent of deaths from skin cancer are associated with this disease.
The chances of survival from this disease directly depend on the time of diagnosis. Current detection methods typically rely on a visual skin inspection, the effectiveness of which depends on the doctor’s skill.
