Did you see Dr. Tim Johnson on Good Morning America a couple of months ago explaining optical frequency-domain imaging (OFDI) technology, which is giving researchers their first-ever detailed look at the interior of human coronary arteries?

Used during heart surgery, the technique enables 3D, microscopic views of significant segments of patients' arteries, letting surgeons see lipid and calcium deposits, and immune cells that could indicate inflammation, in addition to stents. In an illustration of the technique’s practicality, a discussion during BiOS/Photonics West a couple of weeks ago centered on the technique’s usefulness for helping heart surgeons decide where to place stents so as to avoid complications. A video clip of Johnson’s presentation is available on ABC’s site.

The multiple benefits of multifunctional aesthetics
An increasing trend in aesthetic laser systems--for skin rejuvenation, hair removal, skin tightening, tattoo removal, and so on--is multifunctionality. A related trend is promotion of the devices in terms of cost savings and increase of revenue streams for practitioners. Two examples of this are announcements made this month by Candela and Sciton.

I suppose this trend is simply evolutionary, but in light of current economic conditions, especially in the aesthetics realm, it seems especially fitting.
Sciton noted that its new Joule product would enable "revenue stimulus for the current economic environment that will easily translate to solid, long-term practice-building and growth." Perhaps the translation will be easy, but I doubt it will be quick. I hope I’m wrong, though.

Biosensors advancing
“Optical biosensors have begun to move from the laboratory to the point of use,” wrote Frances S. Ligler of the Naval Research Laboratory’s Center for Bio/Molecular Science and Engineering, in a paper titled “Perspective on optical biosensors and integreated sensor systems” (published in December 2008 by the American Chemical Society).

Ligler of the Naval Research Laboratory’s Center for Bio/Molecular Science and Engineering, in a paper titled “Perspective on optical biosensors and integreated sensor systems” (published in December 2008 by the American Chemical Society). Ligler adds that movement from lab to application will be hastened by “new concepts for molecular recognition, integration of microfluidics and optics, simplified fabrication technologies, improved approaches to biosensor system integration, and dramatically increased awareness of the applicability of sensor technology to improve public health and environmental monitoring.”
Here are a couple of interesting stories we’ve reported recently on biosensors. Stay tuned for more:
Spanish researchers propose low-cost method of developing label-free optical biosensor chip
Euro researchers' wearable fiber-optic biosensors monitor patients during MRI scans
