This project aims to understand ion-electron interactions relevant to bioelectronics, and create transducing interfaces. Bioelectronics is a frontier field which aims to connect biological systems with modern electronics and so create biomedical devices. Transducing ion and electron signals using a biocompatible functional interface is difficult since ion and electron physics are different. By combining individual transducers, this project intends to demonstrate ground-breaking bioelectronic logic capable of interface-level processing. The stretch goal is to test this new logic with a biological neuronal model. The project could deliver new science and interfacing elements to integrate tissue and circuitry, and demonstrate these in a real biological model.Read moreRead less
Advanced photonics with flexible pixels in liquid crystals. Similar to conventional pixels in liquid-crystal displays, the localised micro-defects in liquid crystalline structure can be generated by laser beams and immersed particles. The project will create such reconfigurable, or flexible, pixels for efficient control of optical signals underpinning the development of advanced photonic devices.

This project aims to develop a foundation for understanding how microscopic topology and intermolecular interactions control the flow behaviour of supramolecular polymer networks. Brownian dynamics algorithms will be developed to unravel the complex dynamics of the network and calibrated by comparison with carefully designed experiments. The expected outcome of the project is a quantitative framework for connecting the molecular structure and energy landscape with resulting macroscopic properties. This project should yield significant benefit in the rational design of supramolecular systems in which the thermorheological properties can be tuned over a wide range of force/time scales with applications spanning from enhanced oil recovery to injectable hydrogels.Read moreRead less
The geometry of genome access: lessons from HIV. Access to the cell’s nucleus, and hence its genome, is of deep scientific and commercial significance. It is controlled by a phase-separated diffusion barrier within the nuclear pore complex. Recent evidence, however, has shown that HIV can cross this barrier with its protective capsid intact, despite it being over one thousand times larger than the limit for passive transport. Combining concepts from soft-matter physics with recombinant assays, t ....The geometry of genome access: lessons from HIV. Access to the cell’s nucleus, and hence its genome, is of deep scientific and commercial significance. It is controlled by a phase-separated diffusion barrier within the nuclear pore complex. Recent evidence, however, has shown that HIV can cross this barrier with its protective capsid intact, despite it being over one thousand times larger than the limit for passive transport. Combining concepts from soft-matter physics with recombinant assays, this project aims to uncover the link between the unique geometry of HIV capsids and their ability to subvert the nucleus’ defenses. The expected outcome is a step-change in the understanding of nuclear access control, with downstream benefits to virology, bio-engineering and bio-technology.Read moreRead less
Rational design of new synthetic antifreeze molecules for cryopreservation. This project aims to synthesise new carbohydrate-based surfactants optimised for use as cryoprotectants, and to accurately measure, model and optimise their performance.

This project aims to synthesise new carbohydrate-based surfactants optimised for use as cryoprotectants, and to accurately measure, model and optimise their performance. The project will use state-of-the-art experimental methods and advanced phase-field modelling techniques to optimise the cryoprotectants so that they reduce osmotic stress in cells and inhibit ice crystal growth during freezing and thawing. The expected outcomes will be novel cryoprotectants that are easy to synthesise, non-toxic and effective, opening up new possibilities for the cryopreservation of cells, organs and possibly even whole organisms. This will have broad impact in critical applications such as long-term blood storage, reproductive technology and stem cell therapy, as well as preservation of endangered species.Read moreRead less
Meta-microscopy of insect tissue: How nature grows bicontinuous nanosolids. Several butterfly species grow a complex nano-sculptured matrix whose chiral network structure confers remarkable optical properties, including jewel-like reflections. The formation process remains mysterious and a spectacular case of bottom-up self-assembly at far larger scales than accessible in the lab.

Several butterfly species grow a complex nano-sculptured matrix whose chiral network structure confers remarkable optical properties, including jewel-like reflections. The formation process remains mysterious and a spectacular case of bottom-up self-assembly at far larger scales than accessible in the lab. The project aims to decipher this process, by (a) tomography of a species where arrested growth sites represent time-frozen snapshots of the development, and (b) by a combination of micron-resolved in-vivo microscopy of a developing butterfly wing with a growth model to infer nanometer-scale information. This insight will lead to blueprints for self-assembly strategies and shed light on function and form of inner-cellular membranes. Read moreRead less
