Second harmonic generating (SGH) nanoprobes

A new type of nanoprobe is introduced for in vivo imaging, circumventing many of the limitations of classical fluorescence probes. These second harmonic generating (SGH) probes are nanocrystals that converts two photons into one photon of half of the wavelength under intense illumination. Unlike fluorescent probes, they don't photobleach or saturate with increasing illumination intensity.

The report onf SGH nanoprobes is reported in July issue of PNAS. Click here to read more..
