Defining mechanisms of action of novel alpha-conotoxins at nicotinic receptor-channels. Marine snails from the waters off the Australian coast produce an amazing variety of mini-proteins in their venoms called conotoxins that they use to capture prey. These conotoxins bind very specifically to receptors in our body associated with the transmission of nerve signals. We will use natural and synthetically modified conotoxins to selectively block particular types of neuronal 'receptors' to gain a gr ....Defining mechanisms of action of novel alpha-conotoxins at nicotinic receptor-channels. Marine snails from the waters off the Australian coast produce an amazing variety of mini-proteins in their venoms called conotoxins that they use to capture prey. These conotoxins bind very specifically to receptors in our body associated with the transmission of nerve signals. We will use natural and synthetically modified conotoxins to selectively block particular types of neuronal 'receptors' to gain a greater understanding of how the nervous system functions. This knowledge will help in the design of new drugs to treat a variety of diseases and disorders. Essentially we will use a chemical armoury developed by the cone snail to design state-of-the-art mini-protein drugs.Read moreRead less

Making peptides orally bioavailable. Bioactive peptides are exceptionally useful molecules, however to fully realise their exciting applications key limitations need to be overcome: they can't be delivered orally and they do not last long in the body. This project aims to develop a molecular tag that can dramatically enhance both the oral absorption and time in the body of a peptide. This will include identifying the key elements of the tag required for function, the breadth of peptide cargoes i ....Making peptides orally bioavailable.

This project aims to develop new strategies to better synthesize ultrathin Metal-organic framework (MOF) membranes by nanostructured and chemically functionalized substrates. MOF materials have enormous potential due to the extraordinary structural and chemical diversity of these crystalline microporous materials and their potential applications in gas storage, separation, catalysis and sensing. However, a major challenge is fabricating thin robust MOF films or patterns on porous, flexible, and nonporous substrates, quickly and easily in order to construct useful devices. The project will grow ultrathin layers of molecular sieving and electroactive MOFs to produce technology platforms for large scale device manufacturing.Read moreRead less
