Breath analysis for detection of viral infection, the current position of the field (2020)
Journal Article
Gould, O., Ratcliffe, N., Król, E., & de Lacy Costello, B. (2020). Breath analysis for detection of viral infection, the current position of the field. Journal of Breath Research, 14(4), https://doi.org/10.1088/1752-7163/ab9c32

The COVID-19 pandemic has highlighted the importance of rapid, cost effective, accurate, and non-invasive testing for viral infections. Volatile compounds (VCs) have been suggested for several decades as fulfilling these criteria. However currently v...

From fast identification to resistance testing: Volatile compound profiling as a novel diagnostic tool for detection of antibiotic susceptibility (2019)
Journal Article
Smart, A., de Lacy Costello, B., Ratcliffe, N., Drabinksa, N., & Hewett, K. (2019). From fast identification to resistance testing: Volatile compound profiling as a novel diagnostic tool for detection of antibiotic susceptibility. Trends in Analytical Chemistry, 115, 1-12. https://doi.org/10.1016/j.trac.2019.03.019

Widespread use of antibiotics has led to the development of antibiotic resistance in many pathogenic bacteria. If effective methods of alleviating this crisis are not applied, a return to high mortality and morbidity of the pre-antibiotic era could o...
