SEATTLE, July 27 -- Photonics North 2005, to be held Sept. 12-14 in Toronto, will feature 130 local and international exhibitors as well as conferences and presentations on topics from nanoparticles in biology to photonics in medicine and nanophotonics.
   Cosponsored by SPIE and the Canadian Photonics Consortium and held at the Toronto Congress Centre, Photonics North 2005 is a regional symposium focused on Canadian and international business and technology innovations in optics and photonics. Conferences will be held during the three-day event on optical biochips and biosensors for nucleic acids and proteins, imaging systems for information acquisition, nonlinear optics, photonic devices, optical communication systems and networks and microwave photonics, among other topics.
   Plenary presentations will feature Julia Levy of Canada's QLT Inc. speaking on "Photodynamic Therapy: Its Present and Future Role in Medicine"; Jeremy Burroughes of Cambridge Display Technology, on "P-OLED Technology for Displays"; Boris Stoicheff, a University of Toronto physics professor emeritus, on "Light in Art"; Robert Mann, a University of Waterloo physics and applied mathematics professor, on "The Light Side of Relativity"; and Brian Wilson, head of the division of biophysics and bioimaging at the Ontario Cancer Institute in Toronto and a professor of medical biophysics at the University of Toronto, on "Biophotonics: From Lab to Clinic."
   The International Photonics Forum, which we be held during Photonics North 2005, will enable participants to discuss opportunities for international research and industrial partnerships. Proposed topics include research collaborations, business partnerships, investment opportunities, advances in biophotonics, automotive applications and international intellectual property issues.
