The facility will enhance the proposers' capabilities in the area of the fundamental and prototype-type research on biomolecular/cellular devices. The ultimate goal of these projects is to thrust Australian science in the era when the essential functions of cells can be replicated and controlled on devices that are smaller than living cells. The proposed facility has a modular structure consisting of additional nano-positioning, confocal microscope and zeta potential modules built on the existent laser tweezers/scissors, picoliter pipette and Atomic Force Microscope modules.Read moreRead less

Innovation in biomedical research is driven by technology in optical imaging. Optical imaging methods including polarisation microscopy are widely accepted and are at the forefront of biomedical scientific discoveries. This project undertakes fundamental and applied research innovatively combining polarisation imaging and quantitative phase imaging microscopy to uniquely quantify the physical thickness and morphology of birefringent specimens such as the cardiac muscle cell. This project, while of substantial intellectual merit in its own right, could also have the potential to lead to the detection of the mechanisms related to heart failure. Read moreRead less
Cytorefractometry - a new technique for refractive index tomography of living cells. An ultrahigh-resolution bifocal optical coherence refractometry is proposed, and will result to micron-scale-resolution refractive index tomography of living cells, termed cytorefractometry. This technique represents an extension from bifocal optical coherence refractometry that has recently shown a remarkable promise for direct, several-frames-per-second, motion-artifact-free determination of refractive index ....Cytorefractometry - a new technique for refractive index tomography of living cells. An ultrahigh-resolution bifocal optical coherence refractometry is proposed, and will result to micron-scale-resolution refractive index tomography of living cells, termed cytorefractometry. This technique represents an extension from bifocal optical coherence refractometry that has recently shown a remarkable promise for direct, several-frames-per-second, motion-artifact-free determination of refractive index in turbid media, including biological tissue in vivo. We propose to apply our novel technique to study tissue calcification, a serious problem in cardiology, by making use of the refractive index contrast mechanism. Calcification of smooth muscle cells and aorta subdermal implant models will be studied aiming for prevention of calcification-associated pathologies.Read moreRead less

The aim of this proposal is to conduct the collaborative project on multi-photon microscopic imaging through biological tissue, which has been recently initiated between Swinburne University of Technology (SUT) and Massachusetts Institute of Technology (MIT). It will integrate the special skills, two-photon fluorescence endoscopy and second-harmonic coherence tomography, investigated in the respective collaborating institutes, to develop a novel method for detecting/imaging cancer cells that are located at 1 mm below tissue surfaces, while they are still in the early stage to be cured. Consequently, a diagnostic method for early cancer detection particularly through skin tissue becomes possible.Read moreRead less
