Reverse Thermoresponsive Polymers for Sustained Delivery of Therapeutic Agents

Mayadunne R., Balachandra A., Gunatillake T., Lindall C., CSIRO, AU

CSIRO has developed thermoresponsive polymers for encapsulation and sustianed release of bioactives. They are stable aqueous solutions over 24 months, easily pass through a 25 gauge needle at room temperature and immediately gel into a [...]

HDCR: A novel method for the diagnostic detection of methylated DNA for blood based cancer diagnostics

Molloy P., Rand K., Ho T., Lindall C., CSIRO, AU

We have developed a novel technique for specific amplification of rare methylated DNA fragments in a high background of unmethylated sequences that avoids the need of bisulphite conversion. The methylation-dependent restriction enzyme GlaI is used [...]

Gold Nanoparticle Chemiresistors as a Generic Platform for Sensing

Chow E., Raguse B., Wieczorek L., Cooper J.S., Hubble L.J., Webster M.S., Müller K.-H., CSIRO, AU

Thiol-functionalised gold nanoparticle chemiresistors can respond to low-molecular weight chemicals through changes in electrical resistance. This low-cost sensor technology is currently being developed for multiple applications including water quality, microbial metabolomics, environmental monitoring, and point-of-care [...]

Effect of Roughness on Wettability of a Surface by Nano-droplets: Correlation With the Slip Length in Nanofluidics

Jabbarzadeh A., The University of Sydney, AU

Surface characteristic govern friction, flow, wettability and many other properties in solid-liquid interfaces. Wettability of surfaces is usually determined by measuring the contact angle of a single droplet put on the surface. Liquid repelling surfaces [...]

Fast, robust and simple all optical far-field nano-positioning measurements

Juan M.L., Tischler N., Fernandez-Corbaton I., Zambrana-Puyalto X., Vidal X., Molina-Terriza G., QISS, AU

We present a novel method for the nano-positioning measurement of a sample relying on symmetry considerations. In particular, we exploit the cylindrical symmetry of a control defect appended to the sample. The exact nature of [...]

Bio-ink for inkjet printing of living cells

Ferris C.J., Gilmore K.J., Beirne S., McCallum D., Wallace G.G., in het Panhuis M., ARC Centre of Excellence for Electromaterials Science (ACES), AU

This abstract summarises our recent work on the development of a bio-ink tailored for the controlled deposition of cells by inkjet printing. Direct printing of living cells is an emerging approach to the fabrication of [...]

Design and Analysis of Vibration Based Energy Harvester for Precision Agriculture

Aris H., Fitrio D., Singh J., La Trobe University, AU

The world population has increased by more than double in the past three decades and as a result the food supply required per capita has tremendously increases. However, as reported by United Nation Food and [...]

Film Bulk Acoustic Wave Resonator (FBAR) Filter for Ku-band Transceiver

Izza N., Nor M., Shah K., Singh J., Sauli Z., La Trobe University, AU

In this work, the optimisation and analysis of the Ku-band FBAR using 3-D finite element modelling (FEM) is presented. The estimation of material damping coefficients (α and β) using the Akhieser approximation is carried out [...]

The influence of technique on the measured particle size distribution of complex nanoparticle systems

Jämting Å.K., Roy M., Catchpoole H.J., Lawn M., Babic B., Coleman V.A., Herrmann J., National Measurement Institute Australia, AU

Accurate and reliable characterization of nanoparticles is crucial for both industrial applica-tions and studies of their toxicological and environmental impacts. Particle size distribution (PSD) has been widely recognised as one of the key parameters that [...]

An emerging method for the separation and characterisation of manufactured nanoparticles in complex environmental samples

Chekli L., Phuntsho S., Kandasamy J., Shon H., University of Technology Sydney, AU

Manufactured nanoparticles (MNPs) are increasingly released to the environment. In spite of this growth, information about the fate and toxicity of nanoparticles in the environment is limited, partly due to the lack of techniques capable [...]
