Synergistic nanostimulation of nerve cells using atomic force microscopy technology. The research will develop multifunctional nanoelectrodes for neural prosthetic devices of the future. They will be smaller and more effective, enabling integration with single neural networks in the body, to improve the clinical treatment of severe neurological disorders and loss of sensory (hearing and vision) and motor functions.
Developing a multicomponent platform for targeted gene delivery. Gene delivery systems are important tools in biological research and offer many exciting future prospects. Delivering gene material is very difficult in practice: rapid deterioration, poor cell uptake, and reaching the right tissue and cell types are major obstacles. Ways to overcome each barrier individually have been suggested in existing research but these components have not yet been combined in a single solution, which this pr ....Developing a multicomponent platform for targeted gene delivery. Gene delivery systems are important tools in biological research and offer many exciting future prospects. Delivering gene material is very difficult in practice: rapid deterioration, poor cell uptake, and reaching the right tissue and cell types are major obstacles. Ways to overcome each barrier individually have been suggested in existing research but these components have not yet been combined in a single solution, which this project will tackle. This proposal aims to create a technology to stabilise and deliver active gene material to target cells. The gene delivery tool developed in this project will advance biological research greatly with many potential future applications.Read moreRead less

Mucus control: Applying concepts from bacteriophage-mucus interactions. This project aims to examine how mucus-adherent bacteriophage interact with bacteria in mucus as a mechanism to manipulate microbiomes. Bacterial infections at mucosal surfaces in animals are a serious global health threat. Traditionally antibiotics have been used to curb mucosal infections, but antibiotic resistance means new therapies are urgently needed. Bacteriophage – viruses that infect bacteria – can kill bacteria and ....Mucus control: Applying concepts from bacteriophage-mucus interactions. This project aims to examine how mucus-adherent bacteriophage interact with bacteria in mucus as a mechanism to manipulate microbiomes. Bacterial infections at mucosal surfaces in animals are a serious global health threat. Traditionally antibiotics have been used to curb mucosal infections, but antibiotic resistance means new therapies are urgently needed. Bacteriophage – viruses that infect bacteria – can kill bacteria and might provide a layer of antimicrobial immunity in animal mucus. The anticipated outcomes are resolving how bacteriophage control bacteria within mucus, and applying concepts to bioengineer mucosal microbiomes.Read moreRead less
Regulation of 3D Cell Migration by Microtubule-Dependent Processes. The overarching aim of this research is to elucidate the molecular mechanisms that cells use to move in 3D environments: a basic biological function essential to development and homeostasis. During these processes, cells interact with their surroundings where they translate biophysical forces into biochemical signals to adapt their shape to move. This requires distinct signalling, controlled in space and time, to regulate the cr ....Regulation of 3D Cell Migration by Microtubule-Dependent Processes. The overarching aim of this research is to elucidate the molecular mechanisms that cells use to move in 3D environments: a basic biological function essential to development and homeostasis. During these processes, cells interact with their surroundings where they translate biophysical forces into biochemical signals to adapt their shape to move. This requires distinct signalling, controlled in space and time, to regulate the crosstalk between organelles and the cytoskeleton. To date, the role of microtubules remains elusive. Using interdisciplinary approaches combining advanced imaging technology with novel cell biology methods, the project aims to uncover fundamental knowledge about how cells interact with their environment.Read moreRead less
Using lasers to prime the immune system. This project aims to detail the precise effects that lasers have on eye cells, cell populations and the body as a whole. Laser treatments for sight problems are increasing but the effects of these laser applications on the unique immune systems of the eye and brain are unknown. Previous work of the researchers has shown that a novel nanosecond laser when targeted to the eye can alter cells in the lasered eye and in the unlasered eye and the brain. This kn ....Using lasers to prime the immune system. This project aims to detail the precise effects that lasers have on eye cells, cell populations and the body as a whole. Laser treatments for sight problems are increasing but the effects of these laser applications on the unique immune systems of the eye and brain are unknown. Previous work of the researchers has shown that a novel nanosecond laser when targeted to the eye can alter cells in the lasered eye and in the unlasered eye and the brain. This knowledge may be crucial for enhancing our understanding of the immune privileged state of the eye. In addition, it seeks to guide the development of future low energy lasers as important successful treatments.Read moreRead less
Tuning Molecular Translocaton by Close-Field Electroporation. This project aims to determine the underlying mechanisms by which DNA and other molecules are able to migrate across the cell membrane in response to highly localised electric fields. It has recently been shown that focusing of electric fields at the cellular level, using an array of small electrodes, results in unexpectedly high cell transfection efficiencies. It has been termed 'close-field electroporation'. Here it is proposed t ....Tuning Molecular Translocaton by Close-Field Electroporation. This project aims to determine the underlying mechanisms by which DNA and other molecules are able to migrate across the cell membrane in response to highly localised electric fields. It has recently been shown that focusing of electric fields at the cellular level, using an array of small electrodes, results in unexpectedly high cell transfection efficiencies. It has been termed 'close-field electroporation'. Here it is proposed to establish the properties of the electric fields around cells and cell membrane interactions with these fields that enable molecular translocation. This fundamental science could have broad implications in the domains of drug delivery, gene therapy and neural stimulation.Read moreRead less
Understanding platinum dissolution in biomedical stimulating electrodes. Platinum is the main material used in electrodes for neurostimulators like the cochlear implant. Platinum electrodes can experience dissolution during implantation, which can impact on their function. The mechanisms governing this dissolution process are complex and still not fully understood. This research aims to understand the chemical, electrical and biological factors that impact on platinum dissolution in electrodes. ....Understanding platinum dissolution in biomedical stimulating electrodes.

Platinum electrodes can experience dissolution during implantation, which can impact on their function. The mechanisms governing this dissolution process are complex and still not fully understood. This research aims to understand the chemical, electrical and biological factors that impact on platinum dissolution in electrodes. It will also develop new 3D models to simulate conditions in the human body for more rapid testing of electrodes. The new knowledge generated will improve the accuracy of predictions of platinum dissolution, develop new approaches for minimising dissolution, and contribute to reducing need for animal experimentation.Read moreRead less
Development of a multicomponent delivery system for oligonucleotides. Gene therapy has the ability to prevent faulty genes from causing disease, however the ability to deliver genetic material into specific cells remains a major barrier. Our research will overcome this hurdle by generating systems that are superior to existing technologies.
How filopodia connect macrophages to the outside world. Fundamental to life is the ability of cells to sense their surroundings and respond accordingly. This project aims to generate a biological understanding of how certain immune cells carry out such processes, thus enabling them to combat infections.
