Deeper understanding of cell physiology and intra- and inter-cellular communications requires significant improvement in both spatial resolution and in image acquisition rate [1, 2]. To this end we propose to develop and test in-vitro novel fluorescent probes based on germanium, gold and carbon quantum dots. Our goal will be to understand and exploit relationships between synthesis conditions, atomic structure and origins of light emission. Probes will be optimised (for size, QY, etc.) and tested in-vitro on neuron cell lines followed by tests in brain slices to assess probe functionality deep in living tissue.
