Fluorescence is an exquisitely sensitive and extremely versatile tool for interrogating all manner of materials and is ideally suited for biological samples. In this talk the use of single molecule detection to achieve super-resolution fluorescence microscopy with spatial resolution an order of magnitude improved over the diffraction limit of light will be described including instrumentation and image rendering. The importance of benchmarking and potential image artefacts and how to recognise and avoid them will also be discussed. The talk will be illustrated throughout with examples of research performed in my group and with collaborators covering nanomaterials and biological systems including key cellular components such as microtubules, actin and mitochondria. Recent progress in imaging microtubules in cells transfected with proteins from Rhabdovirus (the causative agent of rabies) will be presented.
