A method combining a fixed-wavelength laser with a nondescanned hyperspectral detection system renders clean images. Two-photon microscopy (TPM) is the method of choice for imaging biological samples in vivo, with cellular resolution in three dimensions. Multicolor imaging with several fluorophores – standard in single-photon microscopy – also is desirable in TPM, but existing approaches using multiple lasers are expensive.

SERS on the Verge of Diagnostic Success
Applications poised to benefit from this emerging Raman technology include biology, forensics and pharmaceuticals. After years of exclusion as an academic technique, Raman spectroscopy has finally, firmly taken its place as an important analytical tool used for applications ranging from noninvasive imaging for diagnostics to in-field sensing for the detection of drugs and explosives.

Raman Technique Offers Promise for Clinical Applications
Researchers have achieved some success in honing the sensitivity of this label-free technique for diagnostic applications. Raman imaging has been explored for a range of uses; among the most exciting of these are applications in the biomedical arena. Here, especially in the past decade or so, considerable attention has been paid to the potential of the technique for diagnosis of disease.

Fast Camera Tracks Agile Survival Artists
Some like it hot – for example, micro-organisms that live in the deep sea on “black smokers,” where heat rises from the interior of the earth. These archaea, or “ur-bacteria,” form a separate branch in the phylogenetic tree of life and are veritable survival artists. Biologists have long wondered how exactly it is that archaea propel themselves.
