We have few extra seats (3) for the practical sessions. The opening lecture will be on Dec 12th, Italian Institute of Technology, Diaspro Lab, 2 p.m. Opening Lecture is open without registration need. Opening Lecture by Peter Saggau on Advanced Optical Imaging for Reverse-Engineering the Brain. Lectures on Super resolution Methods and Nanoscopy based on targeted and stochastic readout (IML-SPIM, FPALM, STORM, STED, GSDIM etc..) will be given by Paolo Bianchini, Benjamin Harke, Francesca Cella Zanacchi and Giuseppe Vicidomini with insets by Silvia Galiani and Zeno Lavagnino.

To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** These are known as solid immersion lenses, and they certainly do exist. From the little that I understand the idea is that the lens is within the evanescent field so that the refractive index appears to be continuous to the sample. I'm sure there optics people on this list who could give a better explanation. Whether you could get one to fit a standard microscope is a different question entirely, but if you are working on an optical bench I'd imagine the usual suspects could oblige.

But when you need to continuously exchange solutions, especially while keeping everything at 37C, it becomes a little inconvenient. A Bioptechs flow chamber with a thin spacer works well when cells can be grown on glass, but for cells on a plastic dish the simplest thing would be simply to bring the objective close enough to the bottom. The working distance of common water-immersion objectives is too large for that.
