Radio-magnetic nanoparticles as bimodal positron emission tomography/magnetic resonance imaging contrast agents for dendritic cell tracking. Biomedical imaging is limited by a lack of commercial dual-mode contrast agents, which may be simultaneously used for magnetic resonance (MR) and positron emission tomography (PET) imaging. This project will develop a nanotechnology-based biocompatible dual-mode contrast agent for simultaneous PET and MR imaging, reducing associated side effects.

This is a type of barcoding of organism DNA that allows for rapid gene identification. This technology aims to address a significant need for rapid, on-the-spot identification of organisms. Applications include rapid identification of pathogenic bacteria in infections and identification of organisms in environmental sampling. Current methods are relative slow, require DNA amplification and specialised laboratories.
This proposal aims to fine tune the properties of the large nanopore, polyC9, with respect to size and charge, as well as to identify and characterise novel large nanopores. Read moreRead less

Nano infrared and sub micron raman spectroscopy and imaging: Near-field Infrared (IR) spectroscopy and imaging systems will be coupled to near-field scanning optical microscopes to provide IR spectroscopy and molecular images at less than 20 nanometre lateral resolution. This is unprecedented resolution for infrared fingerprinting and molecular imaging. For two months a year the spectroscopy system will be coupled to the IR beamline at the Australian synchrotron, to provide full IR spectral coverage available to all Australian and New Zealand scientists. A confocal raman spectrometer will be upgraded to the ultraviolet to provide spectra at less than 150 nanometre resolution. These systems will provide a unique Australian resource for nanoscientists, biomedical researchers and materials scientists requiring molecular information on the nanoscale.Read moreRead less
Bacterial detection and infection control using tethered membranes. This project will develop a rapid diagnostic tool to detect live bacteria, which will subsequently reduce risk of infection, increase efficiencies in patient care and hospital management, and produce savings in health care budgets. It also has the potential to save lives through addressing the serious and growing problem of antibiotic resistance.

This project aims to develop a nanoprobe using an X-ray excited luminescence “nanolaser” as the local light source to activate coupled responsive photoacoustic sensors. In-situ imaging of specific biomarkers at the molecular level is key to understanding their roles in physiological and pathological processes, but current imaging techniques using fluorescent probes cannot detect biomarkers in deep tissues due to shallow light penetration. By capitalising on the tissue penetrating property of X-rays and acoustic waves and collecting acoustic waves as the read-out signal, real-time monitoring of biomarkers in deep tissues could be achieved, advancing detection technology for deep-tissue biomarkers.Read moreRead less
