A study in the journal Nano Letters utilized gold nanoprobes to identify stem cells through surface-enhanced Raman spectroscopy. Researchers at the University of Southampton and University of Cambridge used the approach to distinguish cells so the correct lines could be used for therapeutic applications. "In addition, the technique can also allow us to see if drugs are working effectively in cells and can also be used to diagnose diseases as well as treat them," said researcher Sumeet Mahajan.
