Surface-enhanced Raman spectroscopy (SERS) is a powerful tool for detecting and analyzing chemicals. The technology has recently emerged as a non-invasive tool for imaging cells and detecting cancer. Compared with fluorescence microscopy and other conventional fluorescence-based imaging techniques, SERS does not suffer from the problem of photobleaching-degradation of the fluorescence of the probes used as a result of repeated light exposure.

Bioimaging with two-photon excited fluorescence microscopy: Nuclei are complex, well-defined organelles carrying genetic information that is critical to the cell. Visualizing these organelles through fluorescence imaging techniques promises to reveal the mechanisms that govern genetic information and provide ways to predict and treat genetic diseases.
