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

Metaphotonics and metasurfaces for disruptive sensing technologies. This project aims to address a big challenge in nanophotonics by developing revolutionary methods for efficient chiral sensing of molecules without the need for spectrometry, frequency scanning, or moving mechanical parts, and to enhance chiroptical signals a hundredfold with the help of metasurface structures.

This project aims to address a big challenge in nanophotonics by developing revolutionary methods for efficient chiral sensing of molecules without the need for spectrometry, frequency scanning, or moving mechanical parts, and to enhance chiroptical signals a hundredfold with the help of metasurface structures. Resonant metasurfaces are arrays of engineered dielectric nanoparticles with extraordinary characteristics, and they would allow to overcome current limitations of chiral sensing analytical tools. Detecting chiral molecules in low concentrations is crucially important to many fields of biology, chemistry, and pharmacy, as well as to the food and cosmetics industries, constituting a market of tens of billions of dollars.Read moreRead less
Enhancing gravitational wave detector sensitivity and bandwidth for astronomy. This project aims to create small optomechanical devices that amplify the signals in gravitational wave detectors, increasing their sensitivity, especially for higher frequency signals. Calibrated against the 2015 first detection of gravitational waves from black hole mergers, this technology could allow humanity to listen to black holes merging up to 30 times every day, while giving much greater sensitivity to signal ....Enhancing gravitational wave detector sensitivity and bandwidth for astronomy. This project aims to create small optomechanical devices that amplify the signals in gravitational wave detectors, increasing their sensitivity, especially for higher frequency signals. Calibrated against the 2015 first detection of gravitational waves from black hole mergers, this technology could allow humanity to listen to black holes merging up to 30 times every day, while giving much greater sensitivity to signals from smaller black holes and neutron stars. The new technology, which uses nano-scale suspended tiny mirrors controlled by laser light, is likely to have applications in making sensors and quantum devices for advanced instrumentation, improve mineral exploration and measure tiny electromagnetic signals.Read moreRead less

Understanding the origins of the Earth and our Solar System comprises one of the landmark challenges for contemporary astronomy. This project will commission the VAMPIRES instrument which will open a unique window upon planetary nurseries around distant stars. These dusty disks will be perturbed by any newborn planets orbiting within causing several subtle signatures which our instrument is designed to read. Such data will make a critical contribution to our understanding of planetary assembly. Revealing the primordial state, before the onset of structural changes as the system evolves, informs expectations for exoplanetary system architecture and for the chance that life is harboured around distant stars.Read moreRead less
Drawing out spider silk photonics and technology. We discovered certain spider webs are an optical device of amazing sophistication – the result of 136 million years of evolution. New photonic and electron microscopy techniques will measure the unique optical and materials properties of the webs, and the resulting knowledge will have high impact for advanced, self- assembled, photonic materials.
Advanced eyesafe Er:YAG short pulsed lasers for remote sensing applications. This project will develop state-of-the-art tunable pulsed Er:YAG laser systems that will represent a significant advance for eyesafe remote sensing and range finder technologies. It will render obsolete, current state-of-the-art systems for laser ranging and enable remote sensing of a critical greenhouse gas.
The Quantum Dot SPASER. Can we replace electrons with photons in future computers? This project provides two steps toward this goal. By combining advanced materials with ultra-small metallic structures, a new nano-sized form of a laser, called the spaser will be realised. Furthermore, a key component of a computer, a nanoscale modulator, will be demonstrated.
Precision low energy experiments to search for new physics. This project aims to give experimental answers to long existing theoretical questions about the origins and nature of dark matter. Dark matter is a fundamental component of the universe, yet the nature of its composition is still unknown.

This project aims to give experimental answers to long existing theoretical questions about the origins and nature of dark matter. Dark matter is a fundamental component of the universe, yet the nature of its composition is still unknown. There is growing evidence that dark matter is comprised of low mass and weakly interacting particles. By developing ultra-precise measurement tools and new techniques, this project aims to perform a stringent and comprehensive new laboratory search for ultra-light dark matter particles, over likely mass ranges not yet searched. The knowledge gained will provide economic benefits through commercialisation and stimulation of new research and development, and to defence through applications in radar, communications and sensing.Read moreRead less

After a decade of basic research, Nanotechnology is now entering its most disruptive phase. New nanoscale phenomena are being exploited and converted into viable technologies. Plasmonics - the manipulation of light using metal nanostructures - is one of the most promising of these. Plasmonics will enable scientists to achieve optical computing, reach higher data storage densities, and synthesize better catalysts. Other applications include bio-sensing and rapid pathogen detection. To realise these potential outcomes, a leading international cluster focussing on plasmonics will be set up and this cluster will link state-of-the-art materials science, instrumentation and theory.Read moreRead less
