Fluorescent probes for super-resolution imaging of the amyloid architecture. The goal of this project is to develop chemical tools that enable molecular-level imaging of the amyloid structure. The Nobel Prize-winning super-resolution microscopy provides nanoscale imaging capabilities, but surprisingly there have been no substantive efforts to design fluorescent sensors that are compatible with this cutting-edge technology.

The goal of this project is to develop chemical tools that enable molecular-level imaging of the amyloid structure. The Nobel Prize-winning super-resolution microscopy provides nanoscale imaging capabilities, but surprisingly there have been no substantive efforts to design fluorescent sensors that are compatible with this cutting-edge technology. In this project, new fluorescent super-resolution sensors will be developed that enable nanoscale visualisation of amyloid assemblies. These chemical and biochemical studies will establish rational design strategies to develop fluorescent sensors for super-resolution imaging applications and significantly advance our understanding of fundamental differences functional and toxic protein assemblies.Read moreRead less

Combating Antimicrobial Resistance with Bismuth, Gallium and Indium. This research project focuses on the design, development, and application of new bismuth, gallium and indium compounds as antimicrobial agents. These metals act as iron mimics in vivo and can exert antimicrobial activity while displaying low systemic toxicity in humans.

This research project focuses on the design, development, and application of new bismuth, gallium and indium compounds as antimicrobial agents. These metals act as iron mimics in vivo and can exert antimicrobial activity while displaying low systemic toxicity in humans. The project aims to exploit this, and the inability of microbes to easily develop resistance towards metals, to combat bacteria for which modern drugs are rapidly becoming ineffective, as highlighted in the WHO and US Centre for Disease Control list of critical and priority pathogens. The intended outcome is that efficacy will be driven through advances in synthetic and structural chemistry, discovering the mode of action, and creating anti-infective coatings and hydrogels.Read moreRead less
