Summary: Super-resolution imaging techniques based on van der Waals materials. This project aims to address the most pressing challenges in the field of super-resolution fluorescence nanoscopies, which underpin a vast range of biomedical imaging and sensing applications. The project will develop fluorescent probes and new imaging schemes that are simultaneously ultra-bright, photostable, biocompatible and do not require the use of high-power lasers that damage samples during image acquisition. This will be achieved by exploiting unique properties of recently-discovered quantum emitters in van der Waals nanomaterials. The project outcomes will yield a new approach to super-resolution imaging, advance understanding of quantum emitters, and develop new techniques for the processing of van der Waals materials. This is expected to have applications in a diverse range of sectors, and enable new markets in nanotechnology and manufacturing of high-performance Australian-made products.
