An electrocatalytic screen-printed amperometric sensor for the selective measurement of thiamine (Vitamin B1) in food supplements (2019)
Journal Article
Smart, A., Westmacott, K. L., Crew, A., Doran, O., & Hart, J. P. (2019). An electrocatalytic screen-printed amperometric sensor for the selective measurement of thiamine (Vitamin B1) in food supplements. Biosensors, 9(3), Article 98. https://doi.org/10.3390/bios9030098

An electrocatalytic screen-printed sensor has been investigated for the measurement of the biologically important biomolecule vitamin B1 (thiamine) for the first time in food supplements. Under basic conditions, the vitamin was converted to its elect...

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...
