Optical data storage is one of the core aspects of optical information technology which has been globally recognised as one of the next generation high-technology areas that can boost our economy for sustainable development. However, the emergence of blue ray or high-definition DVDs has identified that current optical data storage technology will soon approach the limit of the data storage capacity of approximately 100 Gigabytes. The ground-breaking Petabyte data storage technology we will research will result in the storage capacity of 10,000 DVDs in one disc and thus underpin every sector of our modern life such as remote education, portable banking, global e-security and telemedicine as well as lead to enormous economic benefits in Australia.Read moreRead less

This project aims to develop a platform of diamond nanosensors and novel optical tweezers for probing cellular processes with single-molecule resolution, in vivo and over physiologically relevant time scales. In biomedicine, long-term imaging of single-molecules is beyond reach with existing bio-labels. The project combines the superior properties of nanodiamond biomarkers (brightness, stability, small size and non-toxicity), with new optical tweezers which exploit laser trapping of atoms to manipulate nanodiamonds in three-dimensional biological environments. By accessing smaller size and higher force regimes, the platform will improve bio-imaging and bio-manipulation techniques, and potentially advance pathogentracking and early detection of diseases.Read moreRead less
