Summary
New views of life: quantum imaging in biology. This project will create and apply new technology, based on the quantum properties of diamond, to attack important problems in biology; from how cells differentiate at the beginning of life, to understanding brain function. The results of this project will directly benefit society through the development of new technology for nano-medicine and drug discovery.
Dynamics of constrained Brownian motion of neuro-secretory vesicles. This project will shed light on a fundamental problem the mechanism of brain cell communication by use of quantitative biophotonics methods including laser tracking, optical tweezers and three dimensional fluorescence microscopy. This work will give valuable new clues to finally solve the dynamics of molecular interactions underpinning neuronal communication.
Force microscopy with arbitrary optically-trapped probes and application to internal mechanics of cells. The ability to perform micromanipulation on particles, macromolecules, subcellular organelles, or whole cells is fundamental in elucidating processes such as chromosome movement during cell division, and movement of cell components in and out of the cell. The recent advances in optical tweezers have allowed this type of micromanipulation to approach reality. However, determination of the true ....Force microscopy with arbitrary optically-trapped probes and application to internal mechanics of cells. The ability to perform micromanipulation on particles, macromolecules, subcellular organelles, or whole cells is fundamental in elucidating processes such as chromosome movement during cell division, and movement of cell components in and out of the cell. The recent advances in optical tweezers have allowed this type of micromanipulation to approach reality. However, determination of the true optical force is critical for this technique to reach its full potential. This project will develop novel techniques to quantitatively determine the absolute optical force applied to the cell component using the process of ingestion (phagocytosis) as a proof-of-principle test, and measure forces in chromosome movement and vesicle transport within cells.Read moreRead less

The goal of this project is to develop laser scanning confocal endomicroscopy as a tool for basic scientific discovery and rapid detection of disease biomarkers. The cutting-edge instrument and associated technologies will provide scientists with unprecedented access to dynamic biological processes as they occur in real-time. In addition, it will enable the development of virtual biopsies and instant diagnosis without the need for costly and time-consuming histopathological reports. Thus, it will not only drive transformative research but also transform health care delivery. It will also be a major boost to the Australian biotechnology industry with potential for enormous economic benefits.Read moreRead less

Summary
Brillouin microscopy for high-speed imaging of rigidity within cells. This project aims to improve the sensitivity and speed of Brillouin microscopes. Brillouin microscopes use light to measure the stiffness of samples in 3D without requiring physical access, allowing their use in inaccessible locations such as the interior of cells or within intact tissue. However, Brillouin microscopes are too slow to be used in most research. This project introduces a new approach based on different optical p ....Brillouin microscopy for high-speed imaging of rigidity within cells. This project aims to improve the sensitivity and speed of Brillouin microscopes. Brillouin microscopes use light to measure the stiffness of samples in 3D without requiring physical access, allowing their use in inaccessible locations such as the interior of cells or within intact tissue. However, Brillouin microscopes are too slow to be used in most research. This project introduces a new approach based on different optical physics that is expected to enable faster and more precise imaging. The microscope will be used to study the movement of amoeba, where it is expected to reveal the controlled stiffening and fluidising of the different regions of protoplasm believed to underlie the cell mobility.Read moreRead less
