Three more plenary sessions took place on Tuesday, February 10. Gabriel Popescu of the University of Illinois at Urbana-Champaign discussed the use of optics to bridge molecular and
cellular biology, and presented recent advances in phase-sensi-tive measurements. Thomas C. Südhof of the Stanford University School of Medicine described recent studies showing how
dysfunction of neurexins and their ligands might predispose to
neuropsychiatric disorders. And the evening plenary, hosted by
the International Biomedical Optics Society group (which aims
to facilitate communications between clinicians and engineers),
featured a talk by Stephen Boppart of the University of Illinois
at Urbana-Champaign: Transforming Medicine and Surgery
In the expo hall at both BiOS and Photonics West, exhibitors in the life sciences arena served up product innovation (stay
tuned for detail in future reports) and fun. In addition to Hamamatsu’s mind-control demonstration (see Think Fast!, p. 28), the
Qioptiq booth featured a flow cytometry setup made entirely
of off-the-shelf components (see image) and Edmund Optics
invited attendees to assemble Optics Outreach Kits, including a
laser pointer and prisms, to give to the children in their lives or
to drop in a donation box for an education initiative.
At the Qioptiq booth, Giacomo Vacca of Kinetic River showed off a
flow cytometry setup he assembled using nothing but off-the-shelf
up oxygen” with color change for easy monitoring, and also help
predict the likelihood of DFUs.
2. A fiber-optic spinal probe, designed by postgraduate student Angela Kogler from Stony Brook University (NY), that has the
potential to reduce injuries caused by surgical removal of nearby
tumors. The probe uses differential spectroscopy to measure
blood flow and oxygenation in the spine during surgery. Currently,
these parameters are monitored by sending electrical impulses
via the brain, a method fraught with limitations. Preliminary tests
show accurate, sensitive results and fast response.
3. A laser-based method to deliver stem cells into the retina to
treat macular degeneration and other sight-threatening eye diseases,
by Ygal Rotenstreich, MD, from Israel’s Sheba Medical Center. 2
