Towards real-time measurement of intracellular oxygen tension in patients

Based on the measurement of the emitted delayed fluorescence of endogenously enhanced protoporphyrin IX in a patient?s body, it is now possible to measure oxygen on the level of the mitochondria in a human cell. After one-time calibration, the oxygen tension is derived directly from the measured fluorescence lifetime. For the first time, doctors... von Egbert G. Mik, Erasmus MC ?

Modulated Raman spectroscopy: the gateway into tomorrow?s cancer detection

Early and accurate detection of cancer is crucial to increasing the survival rate of patients. Raman spectroscopy is emerging as a promising novel photonics tool for non-invasive, real-time diagnosis of tissue and cell abnormalities. However, the presence of strong fluorescence background detracts from the use of Raman spectroscopy in routine... von Anna Chiara De Luca, University of St Andrews, UK, and Institute of Protein Biochemistry, National Research Council, Naples, ItalyMichael Mazilu, Elisabetta mehr
