Innovation Extending the frontiers of UK science and industry Fresh light on diagnosis Synthetic biology delivers a new way to fight antibiotic resistance A Matt Hicks Chief Technology Officer of Linear Diagnostics Dr Matthew Hicks is Chief Technology Officer of Linear Diagnostics, and co-inventor of the company’s core technology ntimicrobial resistance is a global health concern, but the statistics are increasingly close to home. In the UK around 5,000 people a year die from antibiotic-resistant bacteria, although some experts believe the figure is much higher. The obvious solution is to develop novel antibiotics – but the way these antibiotics are used will have to change as well. Unnecessary or inappropriate antibiotic prescribing fuels the development of resistant strains, and rapid diagnostics have been highlighted as tools that will reduce this problem. Solutions from synthe tic biology University of Birmingham spinout Linear Diagnostics has developed a diagnostic platform for antibiotic infection and resistance, based on a novel application of linear dichroism, a form of spectroscopy that uses linearly polarised light to measure the alignment of long molecules in a liquid. Long molecules in solution tend to align themselves with the direction of flow of the liquid. In these circumstances, if linearly polarised light is shone through the liquid, it provides a predictable, repeatable signal. This signal will change if the S u mm e r 2 0 17 | U K S PA b r e a kth r o u g h | 3 7
