Order from chaos: Rational design of biointerfacing plasma polymer coatings. The project goal is to facilitate a new generation of bio-interface platforms to be designed using plasma processing. Functionalised plasma polymer surfaces used for bio-interfaces result from random processes in the plasma phase and at the surface. While rules-of-thumb exist for tailoring simple functionalised plasma polymers, detailed knowledge linking plasma processes to surface chemistry is lacking. Using a homologo ....Order from chaos: Rational design of biointerfacing plasma polymer coatings. The project goal is to facilitate a new generation of bio-interface platforms to be designed using plasma processing. Functionalised plasma polymer surfaces used for bio-interfaces result from random processes in the plasma phase and at the surface. While rules-of-thumb exist for tailoring simple functionalised plasma polymers, detailed knowledge linking plasma processes to surface chemistry is lacking. Using a homologous series of precursors, the project aims to unravel physical and chemical plasma processes to enable retention of complex surface functional groups which are critical for subsequent surface processing. This is designed to be achieved by linking plasma physics and chemistry via plasma phase mass spectrometry and surface analysis.Read moreRead less
Design of Tough, Durable and Corrosion-resistant Coatings. Coatings are frequently applied to components operating in harsh environments to enhance durability. Often such coatings exhibit low toughness and poor corrosion resistance that leads to premature failure. The aim of this project is to design, characterise and test innovative coatings that exhibit unique architectures based on natural materials such as teeth and nacre. It is envisaged that these coatings will be hard, tough and durable i ....Design of Tough, Durable and Corrosion-resistant Coatings. Coatings are frequently applied to components operating in harsh environments to enhance durability. Often such coatings exhibit low toughness and poor corrosion resistance that leads to premature failure. The aim of this project is to design, characterise and test innovative coatings that exhibit unique architectures based on natural materials such as teeth and nacre. It is envisaged that these coatings will be hard, tough and durable in hostile, corrosive environments, and will thus, transform industries such as manufacturing, mining and offshore oil exploration as well as enhance the lifetime of prosthetic devices.Read moreRead less
A Tough Resilin Based Hydrogel Platform for Repair and Regeneration. This project seeks to develop novel hydrogels that mimic the properties of the body. In the field of repair and regeneration, our challenge is to make hydrogels that retain the fatigue and resilience properties of the natural body part, but are comprised of nontoxic material. Resilin is a remarkable material exhibiting a broad range of stimuli-responsive behaviour and outstanding elasticity. The project aim is to create a tough ....A Tough Resilin Based Hydrogel Platform for Repair and Regeneration. This project seeks to develop novel hydrogels that mimic the properties of the body. In the field of repair and regeneration, our challenge is to make hydrogels that retain the fatigue and resilience properties of the natural body part, but are comprised of nontoxic material. Resilin is a remarkable material exhibiting a broad range of stimuli-responsive behaviour and outstanding elasticity. The project aim is to create a tough and responsive hydrogel platform from this disordered protein family through greater understanding of structure and mechanical function and incorporating adequate stiffness, strength and biocompatibility. Such tough hydrogels would be applicable to a range of biotechnological applications (eg intervertebral disc repair or artificial skin tissue engineering).Read moreRead less
Nanoscale characterisation of the dynamics of artificial lipid membranes - model systems for drug binding studies. This project will see the development of artificial membranes replicating the physiological behaviour of cell membranes providing a novel platform for in vitro drug evaluation clearing the way for the development of effective new therapies with fewer side effects.
Electrowetting as a tool for measuring the surface energy of solids. Ionic liquids can be forced to spread over hydrophobic surfaces by applying an electric field, thus overwriting their natural tendency to bead. This phenomenon, called electrowetting, can be used to manipulate liquids but also to determine the surface energy of the solid surface which is a key design parameter in many applications.
Mass spectrometry to reveal the role of lipids in protein misfolding. This project aims to develop an integrated mass spectrometry-based approach to determine structures and dynamics of membrane associated proteins, and discover how lipids cause protein misfolding implicated in neurodegeneration. Lipid membranes may influence protein (mis)folding, aggregation and related toxicity. However, the complex and dynamic nature of the lipid-protein interactions involved means traditional methods cannot ....Mass spectrometry to reveal the role of lipids in protein misfolding. This project aims to develop an integrated mass spectrometry-based approach to determine structures and dynamics of membrane associated proteins, and discover how lipids cause protein misfolding implicated in neurodegeneration. Lipid membranes may influence protein (mis)folding, aggregation and related toxicity. However, the complex and dynamic nature of the lipid-protein interactions involved means traditional methods cannot easily characterise them, and they are poorly understood at a molecular level. The project expects to develop tools to bridge a critical gap in structural biology, while understanding lipid-protein interactions could lead to new therapies. This will ultimately provide benefits such as reduced health costs and better health outcomes.Read moreRead less
Understanding the mechanism of two important cytochrome P450 catalysed reactions: dehydrogenation and C-C cleavage. Cytochromes P450 are enzymes that play key roles in drug metabolism and biosynthesis. P450s often catalyse hydroxylation but also carry out important transformations such as dehydrogenation or carbon-carbon bond cleavage. Such reactions are pivotal in many biological pathways. This work will elucidate the mechanism of these transformations and the factors that facilitate their occu ....Understanding the mechanism of two important cytochrome P450 catalysed reactions: dehydrogenation and C-C cleavage. Cytochromes P450 are enzymes that play key roles in drug metabolism and biosynthesis. P450s often catalyse hydroxylation but also carry out important transformations such as dehydrogenation or carbon-carbon bond cleavage. Such reactions are pivotal in many biological pathways. This work will elucidate the mechanism of these transformations and the factors that facilitate their occurrence. This will mainly entail the synthesis of small organic mechanistic probes and determining the structure and stereochemistry of the product of enzymic oxidation. Understanding these mechanisms will allow us to predict when such reactions will occur, enabling their utilisation in for example drug design in the avoidance of the formation of toxic metabolites.Read moreRead less

Combating fungal biofilm growth on surfaces. This project aims to establish a scientific basis for the design and development of thin coatings, for use on biomedical devices, that can resist the attachment of fungal cells and the ensuing formation of infectious fungal biofilms on their surfaces.

This project aims to establish a scientific basis for the design and development of thin coatings, for use on biomedical devices, that can resist the attachment of fungal cells and the ensuing formation of infectious fungal biofilms on their surfaces. Advancing mechanistic understanding of how physico-chemical properties of materials surfaces influence fungal attachment will enable rational development and optimisation of coating chemistries and structures. Tethered antifungal compounds will be added to polymer surfaces by controlled polymerisation methods to provide active deterrence; factors such as conformational flexibility will be studied to optimise coatings, which may will prevent life-threatening infections and reduce healthcare costs.Read moreRead less
