By developing fluorescence pattern-based 3D motion-detection technology in optical tweezers, this project aims to reveal how to achieve nanoscale laser cooling in physiological media. It plans to discover new mechanisms of cooling associated with surface phonons and energy looping in optically trapped lanthanide-doped nanoparticles. Key expected outcomes are technology and a toolset to create interaction between cooled nanoscale objects and biological samples. These are expected to create a research area of biological laser refrigeration, enabling intracellular organelles cooling, nanoscale membrane disruption and high sensitivity force-sensing for integrin study for use in single-molecule biophysics and multimodality subcellular sensing.Read moreRead less

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.Read moreRead less
Dual nanoparticles to distinguish between right and left biomolecules. This project aims to enhance the sensitivity of optical activity to ultralow molecular concentration samples. Optical activity is a commercially available technique used to distinguish chemically identical and morphologically different biomolecules (enantiomers). Unlike other scattering techniques, near-field enhancing of optical activity has not been achieved, thus limiting these measurements to high molecular concentrations ....Dual nanoparticles to distinguish between right and left biomolecules. This project aims to enhance the sensitivity of optical activity to ultralow molecular concentration samples. Optical activity is a commercially available technique used to distinguish chemically identical and morphologically different biomolecules (enantiomers). Unlike other scattering techniques, near-field enhancing of optical activity has not been achieved, thus limiting these measurements to high molecular concentrations. There is evidence indicating that optical activity can be enhanced using dual nanoparticles (ie small particles with the same response to electric and magnetic fields). This project aims to advance our understanding of these dual nanoparticles and experimentally implement their use to enhance optical activity.Read moreRead less
Hybrid plasmonic waveguide for integrated photonic signal processing. Fast processing of information is central to modern society. This task is traditionally carried out by electronics, which however is becoming too slow and energy-consuming for some tasks. Among alternative technologies optics is the most promising, because it is fast and potentially energy efficient, but possible optical solutions are either quite bulky or suffer from high ohmic losses because the light needs to travel through ....Hybrid plasmonic waveguide for integrated photonic signal processing. Fast processing of information is central to modern society. This task is traditionally carried out by electronics, which however is becoming too slow and energy-consuming for some tasks. Among alternative technologies optics is the most promising, because it is fast and potentially energy efficient, but possible optical solutions are either quite bulky or suffer from high ohmic losses because the light needs to travel through metal. This project aims to design and fabricate a device which emits a train of short pulses, a key requirement for any signal processing, and in which the light resides mostly in low-loss material. By using metals merely to confine the light, such a 'hybrid' device would avoid the drawbacks of traditional photonic solutions.Read moreRead less
