The proposed benefits of nanotechnology for industries from material sciences, to bioengineering, energy and the environment are currently driving unprecedented growth in this technology world-wide. Some of these benefits are borne out of the unique properties that different nanoparticles exhibit. However, if nanomaterials pose a threat to the health and well-being of the community, then their risks may outweigh their benefits. This project will identify those characteristics of nanoparticles that can lead to adverse effects and therefore pose a danger to the general community. By defining these characteristics, appropriate changes in nanomaterial production can be considered by industry to minimise these dangers.Read moreRead less

Protein self-assembly on surfaces, interfaces and nanoparticles. Surfaces such as those presented by an air-liquid interface or air-borne nanoparticles exert significant effects on protein aggregation in biological environments. We will develop a comprehensive theoretical and experimental approach to study the effects of such surfaces on the self assembly of proteins leading to disease causing amyloid fibrils. This will provide a molecular level understanding of protein self-association and a ....Protein self-assembly on surfaces, interfaces and nanoparticles. Surfaces such as those presented by an air-liquid interface or air-borne nanoparticles exert significant effects on protein aggregation in biological environments. We will develop a comprehensive theoretical and experimental approach to study the effects of such surfaces on the self assembly of proteins leading to disease causing amyloid fibrils. This will provide a molecular level understanding of protein self-association and a rational basis for the design of inhibitors to stop protein aggregation. The work will also establish design principles for new nanomaterials via the controlled self assembly of proteins on surfaces.Read moreRead less

The capability to design, synthesise and manipulate functional molecules that mimic biological processes will underpin many emerging applications. In this project, macrocyclic metal complexes that catalyse the cleavage of phosphate ester bonds in biological molecules will be developed. Active complexes will be incorporated into nanosized peptide nucleic acid (PNA) - metal complex hybrids and applied as artificial enzymes in the sequence specific cleavage of RNA and DNA. Novel applications of these ?artificial enzymes? in biotechnology are anticipated.Read moreRead less

Chemistry of the Transport of Nutrient Copper in Biological Cells. Nutrient trace metals such as copper are needed for enzymes by living organisms but are toxic in excess. Defects in copper metabolism cause Menkes and Wilson diseases in humans and there are direct connections to neurodegenerative diseases (eg, Alzheimer, Parkinson, Creutzfeldt-Jakob, motor neuron diseases).

Nutrient trace metals such as copper are needed for enzymes by living organisms but are toxic in excess. Defects in copper metabolism cause Menkes and Wilson diseases in humans and there are direct connections to neurodegenerative diseases (eg, Alzheimer, Parkinson, Creutzfeldt-Jakob, motor neuron diseases). It is crucial to understand how healthy cells control toxic but essential copper so that enlightened intervention is possible when disturbances of copper metabolism become pathological. The chemistry of key molecules will be studied to reveal their essential properties and thereby to understand the molecular basis of the copper-linked diseases.Read moreRead less
