Research shows that sexual reproductive stages in yeast (asci) are characterised by in- creased levels of mitochondrial activity. We found that these asci and other fruiting struc- tures are selectively inhibited by anti-mitochondrial drugs such as antimycin A, rotenone, and many more while the vegetative growth i.e. yeast cells and hyphae remained less af- fected. Consequently, bio-assays have been developed where yeast sexual stages are used as indicators to screen for new antifungal, anti-malarial and anticancer drugs or drugs that may pose mitochondrial liabilities. In this study we describe a new imaging nanotechnolo- gy for medical research i.e. Nano Scanning Auger Microscopy (NanoSAM) that can be used in conjunction with these bio-assays to gain more insight into the eff ects and metabolic fate of such drugs. With this nanotechnology cells can now be �dissected� into nanometre thin �slices� while at the same time the chemical composition and 3-D ultrastructure of each �slice�, are assessed
