Tuesday May 31, from 12.00 to 13.00
Seminar with Frédérique Vanholsbeeck, University of Auckland, Department of Physics, Auckland, New Zealand

"Biomedical imaging at the Physics department at the University of Auckland"

During the past years, the biophotonics group has developed several new optical probes based on fluorescence imaging and optical coherence tomography. The fluorescence optical probe (optrode) is a spectrally and time resolved fluorescence probe that allows for example to measure action potential in the beating heart or to monitor bacteria growth and activity in bioremdiation experiments. Optical coherence tomography (OCT) is an interferometric imaging technique that allows high resolution in vivo 3D measurements. Typically the resolution is 1-10 microns with a penetration depth up to 1 mm. OCT fills the gap between confocal microscopy and ultrasound and is currently widely used in ophthalmology. During the talk both techniques will be presented along with some specific applications in which both the optrode or the OCT has currently trialed.
