Researchers at University of Massachusetts Amherst have claimed that they have developed a new sensor array system that can "smell" out different types of cancer cells by detecting microscopic levels of many different metastatic cell types in living tissue.
The sensor array system is made up of gold nanoparticles and proteins and smells out different types of cancer cells in a similar manner through which the human nose can smell different types of odors.
Lead researcher Vincent Rotello said that the only major drawback of the system was that the user should know the appropriate receptor beforehand but added that they have successfully demonstrated the system pre-clinical non-small-cell lung cancer metastasis model in mice developed by researchers at University of Calgary.
