On-demand visible light degradable dental materials. This project aims to break new ground in the field of advanced adhesives by pioneering a unique system that can be cleaved with a defined visible light trigger, enabling the removal of previously bonded material without mechanical force. This would allow two materials to be strongly bonded, including dental crowns, braces and implants. The project will advance on-demand degradable materials design, introducing an advanced class of responsive n ....On-demand visible light degradable dental materials. This project aims to break new ground in the field of advanced adhesives by pioneering a unique system that can be cleaved with a defined visible light trigger, enabling the removal of previously bonded material without mechanical force. This would allow two materials to be strongly bonded, including dental crowns, braces and implants. The project will advance on-demand degradable materials design, introducing an advanced class of responsive networks for applications where reversible bonding is critical. It will have flow on benefits in future dental material applications and also have applications where simple-to-remove, temporary adhesives are required.Read moreRead less

Summary
A flexible virus-like particle delivery platform for next-generation vaccines. Murine polyomavirus (MPyV) capsid proteins self-assemble into spherical protein shells approximately 45 nm in diameter. Such virus-like particles (VLPs) are of considerable interest as bionanotechnological tools. The unique flexibility provided by MPyV VLPs will be exploited by exploring the ability of the interior cavity to retain bioactive cargos while engineering novel functionality on the exterior surface by 'mix- ....A flexible virus-like particle delivery platform for next-generation vaccines. Murine polyomavirus (MPyV) capsid proteins self-assemble into spherical protein shells approximately 45 nm in diameter. Such virus-like particles (VLPs) are of considerable interest as bionanotechnological tools. The unique flexibility provided by MPyV VLPs will be exploited by exploring the ability of the interior cavity to retain bioactive cargos while engineering novel functionality on the exterior surface by 'mix-and-match' assembly of VLPs from modified components. As a proof of concept for next-generation vaccines that stimulate much needed, broadly protective responses against infectious diseases, model antigens will be delivered to specific immune cells using this nano-container.Read moreRead less
Developing orthogonal synthetic signaling cascades. This project proposes a generic approach for the construction of molecular switches based on artificially autoinhibited proteases. The bottom-up design of protein-based signaling networks is a key goal of synthetic biology. Yet, this remains elusive due to our inability to tailor-make signal transducers and receptors that can be readily compiled into defined signaling networks. Using structure-guided design and directed protein evolution, a set ....Developing orthogonal synthetic signaling cascades. This project proposes a generic approach for the construction of molecular switches based on artificially autoinhibited proteases. The bottom-up design of protein-based signaling networks is a key goal of synthetic biology. Yet, this remains elusive due to our inability to tailor-make signal transducers and receptors that can be readily compiled into defined signaling networks. Using structure-guided design and directed protein evolution, a set of protease-based signal transducers and ligand activated allosteric receptors will be created. The developed components are intended to be used to construct artificial signaling networks in mammalian cells that are orthogonal to the endogenous signaling cascades.Read moreRead less

A Facility for Probing Nanostructure in Polymers. The properties of a polymer are only partly determined by its molecular structure. It is now clear that the organization of molecular structure and phase morphology on a nano-scale has an equally important role in determining material behaviour.

The properties of a polymer are only partly determined by its molecular structure. It is now clear that the organization of molecular structure and phase morphology on a nano-scale has an equally important role in determining material behaviour. Increasingly this can be manipulated by judicious choice of formulation and processing variables. The polymer Nano-Structure Facility will bring together Australia's principal polymer experts in this area of structure-property relations and provide them with shared access to the appropriate, modern analytical tools required to probe the nano-structure of such new materials with enhanced properties.Read moreRead less

This project aims to synthesise novel nanocomposite polymers by living radical polymerisation in water and to understand the way polymer microstructure and nanomorphology control material properties. This will provide the enabling science so that nanomaterials with targeted properties can be tailor-made for biomedical and speciality-coatings applications, and thus dispense with the current trial-and-error methodology. The innovations in this project are the novel synthesis of complex polymer architectures in water, and the first quantitative and qualitative structure-property correlations for such materials. This will also result in a deepened understanding of the mechanisms governing the formation of these nanocomposites.Read moreRead less

The project expects that the use of the OFF-switches (as opposed to ON switches) will simplify biosensor design and create a new class of sensory architectures. Integration of OFF-switch-based biosensors with an enzymatic signal amplification circuit is expected to yield ultrasensitive sensory systems with near-real-time response. The project will address a need for new technologies that enable collection of physiological and environmental information rapidly, and at low cost outside of the specialised laboratories.Read moreRead less

While the improved efficacy and selectivity of biomolecules has seen them emerge as alternatives to existing chemicals in health and agriculture, the stability of biomolecules remains a major limiting factor.

While the improved efficacy and selectivity of biomolecules has seen them emerge as alternatives to existing chemicals in health and agriculture, the stability of biomolecules remains a major limiting factor. A general strategy for improving protein stability is by joining the ends of the peptide chain in a cyclisation reaction. While a wide range of cyclic peptides and proteins are being developed in Australia and around the world, the cyclisation reaction presents a significant challenge. In this proposal we detail a novel method for protein cyclisation as a general, low-cost and green production method for making a diverse range of biomolecules. Read moreRead less
