Scientists claim to have developed a sensor array system which can "smell" different cancer types in the same way a human nose can identify and remember different odours. Researchers from the University of Massachusetts Amherst have developed a sensor array system of gold nanoparticles and proteins to detect microscopic levels of many different metastatic cell types in living tissue. In a pre-clinical non-small-cell lung cancer metastasis model in mice developed by Frank Jirik and colleagues at the University of Calgary, Vincent Rotello's team at UMass Amherst used the array sensor system to "smell" different odours.
