BIOMEDICAL IMAGING: MIT researchers obtain 3-D images of living cells
Tomographic phase microscopy can provide detailed images of the activity inside a living cell, without the use of fluorescent markers or other contrast agents that could interfere with the results, according to Michael Feld, director of the George R. Harrison Spectroscopy Laboratory at the Massachusetts Institute of Technology (MIT; Cambridge, MA) and a professor of physics....

OPTOELECTRONIC APPLICATIONS: OPTICAL TOOLS - Trapping with light ...fantastic
First discovered in the 1970s by Arthur Ashkin at Bell Laboratories and further developed by physicists and biologists worldwide in the 1980s and 1990s (many of whom went on to win Nobel Prizes based on their work), optical trapping has become a well-respected research tool for single-molecule and force-measurement studies....

OPTOFLUIDICS: ARROW-based lab on a chip sees one bioparticle at a time
Researchers at the University of California Santa Cruz (UCSC) have created fluid-filled antiresonant reflecting optical waveguides (ARROWs) on a silicon chip to form a tool that, using fluorescence-correlation spectroscopy (FCS), can detect the presence of single nanosize biological particles such as fluorescently tagged liposomes....
