Dear Tony, Martin,

We have Kevin Eliceri speaking at our Photonics Group Seminar in room 
630 Blackett on the 4^th June from 1315-1415, who is from the Laboratory 
for Optical and Computational Instrumentation (LOCI) at the University 
of Wisconsin. FILM users may be interested in his talk.

I will send you the title and abstract as soon as I have it.

This talk will be preceded by one from Steve Jaques, see attached poster 
in Lecture Theatre 2 Blackett at 12pm, which may also be of interest.

best regards,

Chris

Optically probing the nanoarchitecture of cells and tissues
Prof. Steven Jacques, Oregon Health & Science University, Portland, USA

Tuesday June 4th, Lecture Theatre 2, Blackett Tea, coffee and biscuits 
from 11:45, seminar from 12pm

Abstract

Optical measurements are sensitive to structures on the size scale of a 
wavelength of light. Hence, cellular and extra-cellular structures with 
sizes in the range of 200-2000 um dominate optical measurements of 
biological tissues. The contribution from very small structures (<200 
um) is still detectable, however, as apparent "Rayleigh scattering" 
which is significant in tissues with collagen. Two measurements are able 
to discern the size distribution:
(1) Confocal reflectance measurements as the depth position (z) of the 
focus is scanned down into the tissue, ( ) .
(2) Wavelength dependence of diffuse light reflectance.
Such measurements offer an opportunity to assess and monitor the 
nanoarchitecture and microarchitecture of skin and other tissues. 
Detecting the effects of pathology, actinic damage, and pharmaceuticals 
on the skin are potential applications of these non-invasive optical 
methods.
About Prof. Jacques
Steven Jacques has held appointments at the Wellman Center for 
Photomedicine and Massachusetts General Hospital, Harvard Medical School 
and University of Texas. He is currently Professor of Dermatology and 
Biomedical Engineering at Oregon Health & Science University in 
Portland, Oregon. His work continues on developing novel uses of optical 
technologies for both therapy and diagnosis. He developed a hand-held 
polarized light camera to visualize skin cancer margins and guide 
surgical excision, tested in clinical trials and licensed to a company.
Professor Jacques currently works on bridging between the possibilities 
afforded by optical technologies and the needs of molecular and cellular 
biology. In particular, he is developing novel microscopes that are 
sensitive to the ultrastructure of cells and tissues.
