Photo switchable product selectivity control in hydroamincation reactions

Controllable product selectivity is of equal importance to efficient reactant conversion in chemical synthesis. Achieving high selectivity of the desired product is often a significant hurdle since the reactants in synthetic processes are usually heated to achieve a high reaction rate and this heating generally reduces differences between competitive reaction pathways and can create a substancial amount of by-products.An extensive number of studies have been performed to reduce unwanted by-products. If light irradiation applied in photocatalytic selective synthesis could determine …

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 …

New antimicrobials and biofilm eradication agents

Bacteria can readily adhere to the surface of synthetic materials and form a biofilm. This makes it much more difficult to combat than circulating bacteria due to their extreme resistance to antibiotics. Thus, biofilms are of particular concern in the healthcare system, as they can increase infection rates by contaminating medical devices, delay chronic wound healing and contribute to tooth decay. This project aims to design, develop and evaluate new antimicrobial compounds active against biofilms. …

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.

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 …

Design of Free Radical Dynamic Nuclear Polarisation (DNP) Agents

Nuclear magnetic resonance (NMR) is one of the most widely used analytical and structural elucidation techniques in chemistry and materials science.It is also the underlying principle of magnetic resonance imaging (MRI), an important clinical imaging modality.However it is a relatively insensitive technique compared to other spectroscopic methods.This project will look to investigate the synthesis of stable, free-radical compounds with application as magnetic resonance enhancement agents.

Synthesis of robust desalination membranes with high water permeability

The aim of this project is to use in-situ polymerisation to create an interpenetrated network of hydrophilic polymer within the less hydrophilic support layer of desalination membranes. Increased hydrophilicity is expected to increase water flux and hence desalination efficiency without a negative effect on water permeability.

Spider silk: structure, mechanics and processing

Spider silks possess a range of qualities that are rarely found simultaneously in one material, and it is no surprise that an enormous effort has been made to replicate or learn from them.1,2 Toughness, extensibility and strength are only a few of the desirable traits that make spider silk of such interest. Silk is biodegradable and, unlike synthetic high-performance fibres such as Kevlar, it is extremely lightweight.3,4 A further advantage lies in its processing conditions and requirements. Whereas production of …

Programming polymers

Radical polymerisations play a key role in both commercial and fundamental research with it being in 45% of international polymer production at 100 million tons per year.However, radical polymerizations still suffer from synthetic drawbacks like all-carbon polymer backbones, which largely prevent their (bio)degradability.In this project, we will develop novel polymers which can be programmed towards a controlled degradability. Towards this goal, you will develop a polymerization technique that allows to incorporate small natural building blocks (i.e. peptides) into synthetic polymers. …
