Artificially building the bacterial flagellar motor. This project will allow us to learn how nature’s most sophisticated rotary motor works and how to build these artificially, establishing a new field of research into man-made biological machines. This has potential applications for the emerging field of nanotechnology to make nanometre-scale devices that are powered by efficient biological machines.

The ability to study living cells and human biological models (cell cultures) delivers greater understanding of basic biological function and response to applied (bio)chemical stimuli. Creating the physical environments to sustain biological models, and mimic natural conditions and fluidic pathways, is immensely challenging, yet essential to deliver meaningful observational data. This project will deliver this capability through the convergence of expertise and innovation in analytical chemistry, materials science and cellular biology, ultilising the latest technology and understanding of 3D micro/electrofluidics, to enable the study and stimulation of advanced biological models, sustained within precisely controlled 3D micro-environments.Read moreRead less

Summary
Investigating the structural basis of human antibody stability. This project plans to use protein engineering and X-ray crystallography to investigate the effects of stabilising mutations on antigen binding and the antibody-antigen interaction. Monoclonal antibodies are high-affinity reagents that have transformed the study of biological processes. However, antibodies often display inherent instability, which limits applicability. Mutations have recently been identified that render human antibod ....Investigating the structural basis of human antibody stability. This project plans to use protein engineering and X-ray crystallography to investigate the effects of stabilising mutations on antigen binding and the antibody-antigen interaction. Monoclonal antibodies are high-affinity reagents that have transformed the study of biological processes. However, antibodies often display inherent instability, which limits applicability. Mutations have recently been identified that render human antibodies resistant to aggregation. Preliminary data indicates that stabilising mutations improves the biophysical properties of monoclonals without affecting the native antibody structure. The project aims to provide detailed insights into the molecular basis of antibody stability.Read moreRead less
