The aim of this project is to develop the first biosensors that prevent nonspecific protein adsorption and allow reversible protein binding. The project expects to achieve this using a combination of novel surface chemistry and pulsed electric fields that dynamically change a sensing interface. The impact of electric fields on the binding of proteins to this interface will be followed using a novel single molecule fluorescence microscope previously developed that can locate the position of proteins with 2 nanometer resolution. The expected outcomes of this project is a class of biosensor that can continuously monitor protein biomarkers for wearable sensors that provide information on a user’s wellness and nutrition.Read moreRead less

The first generation of single entity measurement tools for analysis: This fellowship project aims to develop a new type of diagnostic device that measures single molecules or single cells. Such measurements seek to revolutionise analysis by allowing heterogeneity and rare events in samples to be identified, rather than the average information provided by existing tools. With single molecule devices, the heterogeneity in response enables the development of multiplexed, calibration free sensors. The outcomes of the project are hoped to be completely new thinking on performing measurements, new knowledge regarding heterogeneity in biology and the potential for novel commercialised sensors. It is expected that this will be important not only in biological discovery, but also in providing far more robust sensors for applications such as environmental monitoring, disease prediction, personalised medicine or drug discovery.Read moreRead less

ARC Research Hub for Integrated Device for End-user Analysis at Low-levels. This hub aims to improve detection of biological materials by building a portable device for rapid, time-critical detection of low-abundance molecular and cellular analytes. It is expected that the resulting technologies would be used at medical points of care, ordinary workplaces and centres of activity to test for tiny levels of targeted molecules. The initial focus would be early diagnosis of disease and point-of-care drug testing for humans and animals, but the technology platform could be used to sample food and environmental toxins. The hub expects these disruptive technologies will make Australian biotechnology, diagnostics, veterinary, agribusiness and manufacturing firms globally competitive.Read moreRead less

The aim of this research is to develop the application of protein nanopores for multiplex identification of DNA samples for ultrafast gene detection. 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
Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined.

Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silicon electrodes where irradiating with light causes an increase in conductivity at the illumination spot. The project will explore the variables that influence the spatial resolution and apply the ideas to making soft connects for nanoelectronics and making high density electrode arrays for electroanalysis.Read moreRead less

This project seeks to gain quantitative understanding of the role of electrostatics over chemical processes. Chemical transformations of organic compounds at interfaces underpin some of the most important processes, from the production of fine chemicals for pharmaceuticals to assisting bio-degradation of pollutants in clean technologies. Recent computational studies suggest that by applying oriented electric fields at interfaces, the rate and the selectivity of chemical processes can be altered at will. The project intends to test these theoretical findings. The knowledge generated by this research may translate into new technologies for the fine-chemical and biotechnology industries.Read moreRead less

New strategies for highly sensitive chemical detection based on luminescent ruthenium and iridium complexes. Chemical reactions that emit tiny quantities of light, not even visible to the naked eye, can be used to detect the biomarkers of disease or traces of chemical or biological weapons in a terrorist attack. This project creates a new generation of reagents for this remarkably sensitive mode of detection for these and other important applications.
