We try to calibrate the combination AFM and confocal microscope with a new software. The goal is to align the image of the AFM with the image of confocal microscope. First, we looked at some ATTO molecules with the confocal microscope and measure the fluorescent lifetimes of the ATTO molecules. Olaf wants to test another way of drying the sample. It is an ACE duster moisture-free for cleaning computers. It contains tetrafluoroethane which is heavier than air. He intends to spray some of this gas onto samples in petri-dish. The goal of the new software is to make the AFM tells the confocal microscope the position of the cantilever and whether it touches the surface.
