A new imaging technique using mid-infrared photothermal imaging has been developed that can reveal a range of intracellular processes. This technique is the first to be able to detect the nanoscale changes in temperature inside cells, with potential implications for cancer diagnosis and drug development. The technique, developed by researchers at the University of London, is non-invasive and can image cells in a live, unperturbed state. This opens up a range of new opportunities for scientists to study processes inside living cells without the need for invasive procedures.
