This is the area where great efforts were made seeking answers for some of the biggest challenges for Human kind. All the diseases that plague living organisms were the driving force for the applied research made on last decades. Spectroscopy is widely used in this area for studying cell activity and signaling, drugs development and effects among many others. Fluorescence spectroscopy is the selection technic to work with cells together with a range of well-known targets, labels and markers. Also the use of Raman spectroscopy is increasing as the lasers power needed for the analysis is reduced mainly by the use of highly sensitive detectors.
