Summary
Scientists have developed a number of incredibly powerful and sophisticated techniques to identify chemicals and measure their concentrations in the laboratory. However, it remains a major challenge to perform these measurements under everyday circumstances. For example, surface-enhanced Raman scattering (SERS) has gained widespread recognition as a technique for trace chemical detection, but it remains confined to a small number of specialist laboratories.

However, it remains a major challenge to perform these measurements under everyday circumstances. For example, surface-enhanced Raman scattering (SERS) has gained widespread recognition as a technique for trace chemical detection, but it remains confined to a small number of specialist laboratories. For this reason, Dr Paul Stoddart at Swinburne University of Technology recognised a need for more practical SERS probes for field applications. His team has now developed a proprietary SERS probe, based on an optical fibre that is little thicker than a hair. These optical fibres can form the core element of field-portable SERS spectrometers. This work has recently been boosted by the discovery in the United States that SERS can be used to monitor glucose in blood. The development of a continuous glucose monitor has long been a holy grail of sensor research, because of the millions of diabetes sufferers who regularly perform the painful finger prick test. For SERS to provide a practical solution to glucose monitoring, it is recognised that SERS optical fibres are needed for minimally invasive probes. With support from Biopharmica and the Diabetes Australia Research Trust, Dr Stoddart's team has now demonstrated that sensitive SERS probes can be produced in large quantities. The next objective is to develop a prototype low-cost SERS spectrometer for use as part of a continuous glucose monitoring system. This will require the development of a laser source and spectroscopic system that can interface to the SERS probes. It is proposed to use an Australian designed and manufactured laser system based on a low-power narrow-linewidth laser diode. The project plans to bring together Swinburne University, OptoTech and Grey Innovation in order to develop a commercially scaleable and robust device.Read moreRead less

Summary
Advances in nanotechnology have led to new techniques for the precise fabrication of nanometre scale structures. A recent breakthrough by the applicants now allows high-quality nanostructures to be stamped onto the tip of low-cost optical fibre probes. When coated with silver, these sensitive probes can be used for continuous monitoring of blood glucose in diabetics and in critical care situations. This project aims to develop a prototype manufacturing system for optical fibre glucose probes.
Preterm birth is a major cause of neonatal death and cerebral palsy. This grant will provide proof-of-concept that a computer program can be developed to predict a pregnant woman�s risk of preterm birth. There is a large market (4M US and 8M Europe), there are no competing technologies. This is a unique collaboration between Biomedical Engineering and an Australian centre with an international reputation in preterm birth, assisted by a pathology company.

Summary
The goal of this project is to take a new concept for cardiovascular disease management through the proof-of-concept stage and deliver a novel model for cardiovascular disease management. When proven, the application of this new process for service delivery will provide a low-cost way of closing the gap between guideline recommendations and current management of vascular disease in Australian primary care settings.

Summary
Cancer is often not detected until it has invaded surrounding tissues and spread to other organs. Current treatment is then often ineffective, and prognosis poor. Early detection of cancer is therefore essential for improved disease management. Such methods must be cheap, non-invasive, and rapid with high sensitivity and specificity. We are investigating a new biosensor technology that satisfies these criteria. This method uses magnetically amplified luminescence for the detection of low levels ....Cancer is often not detected until it has invaded surrounding tissues and spread to other organs. Current treatment is then often ineffective, and prognosis poor. Early detection of cancer is therefore essential for improved disease management. Such methods must be cheap, non-invasive, and rapid with high sensitivity and specificity. We are investigating a new biosensor technology that satisfies these criteria. This method uses magnetically amplified luminescence for the detection of low levels of cancer cells in clinical samples (urine, faeces, blood, biopsy), using telomerase as a marker.Read moreRead less

Advanced mapping systems utilize online visualization of catheters, 3D geometry, and annotation of ablation sites. To date, all commercially available systems rely on proprietary equipment to locate catheter positions and reconstruct chamber shape from multiple site recordings. Thus, cost is prohibitive, limiting widespread availability. An alternative approach has emerged with the use of CT-MRI imaging and analysis. Novel techniques extract images of the endocardial surface from CT-MRI for use in electrophysiological mapping. This surface can be used as the chamber geometry instead of reconstruction based on expensive technology measuring spatial coordinates of the catheter tip inside heart. The proposed Anatomical Template Mapping System (ATMS) will generate maps of electrophysiological parameters derived from catheter recordings without the need for proprietary equipment. The physician will direct the virtual catheter position onto the 3D model of the chamber, obviating the need for equipment to map the spatial distribution of the catheters. The major advantage is that, without the need for specialized equipment, this method of mapping is substantially cheaper and can be used with any conventional electrophysiological mapping systems. Furthermore, it will provide the most important feature of the advanced mapping systems - an understanding of the arrhythmia mechanism.Read moreRead less

Summary
Percussion is a valuable clinical method for physical examination of parts of the body. A sharp tap (impulsive force) is applied to the body wall and the sound radiated in response is observed. This sound may be dull (over liver) or stony dull (pleural effusion), or resonant (over normal lung) or hyper-resonant (over bowel). While the variation in radiated sound is not fully understood, it is apparent that the presence of gas, which is highly compliant, increases mobility of the overlying tissue ....Percussion is a valuable clinical method for physical examination of parts of the body. A sharp tap (impulsive force) is applied to the body wall and the sound radiated in response is observed. This sound may be dull (over liver) or stony dull (pleural effusion), or resonant (over normal lung) or hyper-resonant (over bowel). While the variation in radiated sound is not fully understood, it is apparent that the presence of gas, which is highly compliant, increases mobility of the overlying tissue and allows it to resonate; where the sub-tissue is largely fluid, tissue mobility is low and the percussive sound is dull. Percussion is useful for examining the adult chest and lung, but cannot for example be applied in infant intensive care as only limited impulsive force can be used, and the adult finger, which is both a coupling device and sounding board, is too large. As well, percussion requires skill and quiet conditions. Accordingly, we developed a device to measure mobility of the chest and other tissues in real time. The VibroPulse applies a known low-level force to the body surface and records the resultant velocity induced in the surface. The force is generated by a vibrating mass set in motion by an electromagnetic motor driven by pseudo-random noise. Tissue mobility, defined as velocity-force, is derived simultaneously across the frequency range, providing an easily interpreted quantitative output unaffected by ambient noise. This proposal has two aims we can achieve in 1 year: (1) to continue evaluating VibroPulse sensitivity to tissue composition, using symmetrical percussive sites on the human chest and abdomen that are dull on one side and resonant on the other, and the chest of anaesthetised animals with experimentally induced pneumothorax and lung collapse, two life-threatening conditions for which percussion is a key diagnostic method, and (2) to engineer a small device from our bulky prototype that is suitable for clinical use, in infants and adults.Read moreRead less
