Journal Article
Vaughan, K., Shepherd, S. F., McGuire, N. D., de Lacy Costello, B., Ewen, R. J., Jayasena, D. H., …Ratcliffe, N. M. (2014). The use of a gas chromatograph coupled to a metal oxide sensor for rapid assessment of stool samples from irritable bowel syndrome and inflammatory bowel disease patients. Journal of Breath Research, 8(2), https://doi.org/10.1088/1752-7155/8/2/026001

There is much clinical interest in the development of a low-cost and reliable test for diagnosing inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS), two very distinct diseases that can present with similar symptoms. The assessment o...

Towards point of care testing for C. difficile infection by volatile profiling, using the combination of a short multi-capillary gas chromatography column with metal oxide sensor detection. Measurement Science and Technology, 25(6), https://doi.org/10.1088/0957-0233/25/6/065108

Rapid volatile profiling of stool sample headspace was achieved using a combination of short multi-capillary chromatography column (SMCC), highly sensitive heated metal oxide semiconductor sensor and artificial neural network software. For direct ana...

The electrochemical behavior of nitrazepam at a screen-printed carbon electrode and its determination in beverages by adsorptive stripping voltammetry (2009)
Journal Article
McGuire, N. D., Honeychurch, K. C., & Hart, J. P. (2009). The electrochemical behavior of nitrazepam at a screen-printed carbon electrode and its determination in beverages by adsorptive stripping voltammetry. Electroanalysis, 21(19), 2165-2170. https://doi.org/10.1002/elan.200904667

The cyclic voltammetric behavior of nitrazepam was investigated at screen-printed carbon electrodes over the range1.5 V to {thorn}1.5 V. Two reduction peaks were observable on the negative scan, at 0.7 V, and 1.2 V using pH 6 buffer. On the return sc...
