BioOptics World blogging, twittering from BiOS/Photonics West

JANUARY 27, 2009—BioOptics World is making updates to its BioOptics Worldview blog and Twitter account (where you can follow chief editor Barbara Goode,, reporting on research and commercial developments discussed at the BiOS and Photonics West, January 24-29. Following is an example of what you'll find; stay tuned for more!

Introducing the "hot topics" session tonight (Saturday, January 24) at SPIE's BiOS event, Dr. Rox Anderson noted that the BiOS conference is now nearing half the size of Photonics West!

The session itself began with Dr. Stefan Hell demonstrating how his Stimulated Emission Depletion (STED) microscope breaks the diffraction barrier to achieve super-resolution imaging (28X greater than confocal, down to 8 nm) within living neurons, for instance—and record at 28 frames per second. Wow.

In the exhibit hall I found a couple of vendors claiming unique capabilities. For instance, Innolume says its quantum dot technology exploits wavelengths that nobody else touches--in the 1120 - 1210 nm range (actually Innolume covers a wider spread--1064 - 1320 nm--but other companies have offerings at either end of that range). Another, Translume, is using lasers to produce glass waveguides and other microstructures such as microfluidic channels.

Michelson Diagnostics demonstrated its handheld OCT probe for imaging skin. The company is targeting non-opthalmic applications, and in fact plans to attend or exhibit at dermatology events in 2009.

Kapteyn Murnane Laboratories (KMLabs for short), which develops low-cost ultrafast amplifier systems to compete with some of the larger developers, said it shortly plans to introduce a new device about half the size of its current systems.
