Hi-resolution imaging of microscale fracture in osteoporotic bone

Osteoporosis leads to weak bones and debilitating fractures in the elderly. Understanding the biomechanics of osteoporotic vertebral fractures is an essential step in avoiding the morbidity caused by this condition.

Hearing colour and seeing sound – switchable optoacoustic imaging agents

Optoacoustic imaging is a relatively new medical imaging technique. It utilises laser light to excite an imaging agent, which in turn converts this light energy into heat. This heat is dissipated as a sound wave, which can be detected with an ultrasound receiver. This technique aims to overcome the minimal penetration depth of fluorescence imaging, and the lack of molecular specificity of ultrasound.In this project we are aiming to develop and synthesize intelligent imaging agents for optoacoustics, which are able …

Fighting slime with nitroxides and polymers

Biofilms, more commonly recognised as slime, are complex communities of microorganisms, which provide these creatures with a niche where they are able to flourish in conditions where they might not normally survive.Because of this enhanced survivability, bacterial biofilms show enhanced resistance to disinfectant and antibiotic treatment, and are the cause of nearly three quarters of hospital acquired infections. Nitroxides, molecules that possess a stabilised free radical, are able to disperse these biofilms and make them susceptible to treatment.Our research group …

Bio-inspired nanomaterials for sustainable environment

In nature, biological species have evolved optimal structures through millions of years with amazing characteristics and swift stimulus-responsive capabilities, which give inspiration to researchers for the design of smart functional materials. Many of these smart materials have surfaces that dynamically alter their physicochemical properties in response to changes in their environmental conditions and to triggered control of interfacial properties.In this project, novel bio-inspired interfaces and surfaces will be developed for sustainable environment applications, based on the understanding of the relationships …

2D metal oxide nanomaterials for sustainable energy applications

Two-dimensional (2D) transition metal oxide systems present exotic electronic properties and high specific surface areas, and also demonstrate promising applications ranging from electronics to energy storage. Yet, in contrast to other types of nanostructures, the question as to whether we could assemble 2D nanomaterials with an atomic thickness from molecules in a general way, which would give them some amazing properties such as those of graphene, still remains unresolved.In this project, we intend to synthesise well-crystallised, ultrathin transition metal oxide …

New anti-biofilm agents for biomedical implants

The diatomic free radical nitric oxide is a well-recognised signaling molecule in mammals which modulates bacterial existence between planktonic and biofilm modes.Low non-toxic concentrations of nitric oxide disperse a variety of Gram positive and Gram negative bacterial biofilms to free swimming planktonic bacteria.We have recently shown that nitroxides (sterically hindered versions of nitric oxide) can inhibit bacterial biofilm formation and disperse existing biofilms.

Pluses and minuses of lipid mass spectrometry

Lipids are among the most structurally diverse of all the biomolecules and thus deciphering their many functions requires bio-analytical technologies capable of uniquely identifying and quantifying individual molecules in a milieu of many thousands of analogues. Mass spectrometry is the pre-eminent technique for contemporary lipid analysis but is challenged by the preference of certain lipids to ionise with a polarity that affords sensitive detection but does not permit detailed structure elucidation. This project will develop advanced instrumentation capable of on-demand …

Geopolymers

Geopolymers are materials which are rapidly finding interest in industry because they are 90% less polluting than conventional portland cement. They are made by reacting aluminosilicate materials with alkaline solutions in the presence of a reaction promoter.We are examining new geopolymers made from Australian based minerals such as zeolites and clays.

Advanced photoresists for 3D laser lithography

Some estimates state that 30% of all manufactured goods will be 3D printed in 2030. A particular type of 3D printing is 3D laser lithography, where micro- and nano-sized structures can be prepared. These structures find wide-ranging applications in meta-materials, functioning as invisibility cloaks or scaffolds for single (stem) cell interrogation. Today’s inks for 3D printing, however, are limited in their functionality, resolution and the obtainable material properties.This project will develop – in close collaboration with team members QUT's Soft …

Computational design of 2D materials and surface functionalisation for catalytic application

Functionalised two-dimensional nanomaterials have attracted immense interest in materials design by combining the merits of large surface ratio and nano-size functionalisation, and have been able to meet the requirement of a variety of applications, including electronic devices, fuel cell, and catalytic application.Except for their tunable physical properties, of particular interest is their chemical reactivity and surface catalytic applications, because they can be more easily chemically modified by nano-size functionalisation. In this respect, numerous studies have been dedicated to exploring the …
