Project Details


Biofilms are microbial communities linked to over 80% of infections and exhibit remarkable antimicrobial tolerance. We have developed advanced microscopy methods to visualise multi-millimetre-scale biofilms with sub-cellular resolution, providing unique cross-scale 3D overviews. We identified networks of nutrient transport channels and aim to exploit them using targeted biofilm therapeutics. However, we must understand the channel chemical microenvironment to inform new treatments. We present a dual-pronged approach to quantify the oxygen concentration throughout biofilm channel networks using high-resolution oxygen profiling and fluorescent oxygen-nanosensor imaging. These insights will inform the design of a new class of antimicrobial therapeutics to tackle recalcitrant biofilm infections.
