The research team were also able to show that the nano-based sensor could differentiate between melanoma and normal skin cells. The initial findings suggest that a non-invasive, odor analysis could be of high value in early detection and diagnosis of human melanoma. The sensor was created out of nano-sized carbon tubes coated with strands of DNA, and can be bioengineered to recognize a wide variety of targets.
Collaborators with Monell include the University of Pennsylvania and The Wistar Institute. The research is supported by The National Institute on Deafness and Other Communication Disorders of the National Institutes of Health.
