Prebiotics from Marine Macroalgae for Human and Animal Health Applications
Laurie O’Sullivan,B. Murphy,Peter McLoughlin,Patrick Duggan,Peadar G. Lawlor,Helen Hughes,Gillian E. Gardiner +6 more
TL;DR: The concept and potential applications of prebiotics are introduced, followed by an outline of the chemistry of seaweed polysaccharides, which could potentially be exploited as prebiotic functional ingredients for both human and animal health applications.

Determination of Chlorinated Hydrocarbon Species in Aqueous Solution Using Teflon Coated ATR Waveguide/FTIR Spectroscopy
B. Murphy,Peter McLoughlin +1 more
TL;DR: In this article, the potential of an optical sensor based on mid-infrared spectroscopy, utilising a zinc selenide (ZnSe) attenuated total reflectance (ATR) element coated with an amorphous Teflon polymer, to determine chlorinated hydrocarbon species (CHC) in an aqueous environment is examined.

Study of the impact of penetrant characteristics upon diffusion into Teflon membranes to further assess the performance of an ATR/FTIR sensor.
TL;DR: In this paper, the impact of penetrant properties upon diffusion into the enrichment membrane must be characterised. And the results highlight the necessity for full characterisation of the observed effects prior to the development of a sensing technology for real applications.

Modelling of Fickian diffusion to enhance polymer-modified sensor performance
TL;DR: In this article, the authors describe the implementation of mathematical modelling to achieve improved sensor response times and increased sample throughput without compromising performance using an experimental system based upon polymer modified internal reflection infrared spectroscopy.

The development of novel organically modified sol-gel media for use with ATR/FTIR sensing.
Kevin Flavin,J. Mullowney,B. Murphy,Eleanor Owens,Pádraig Kirwan,Kieran Murphy,Helen Hughes,Peter McLoughlin +7 more
TL;DR: This research approach resulted in a mid-infrared sensing methodology in which the properties of the recognition layer could be tailored by variation of the sol-gel precursors and processing conditions, as demonstrated by variation in the rate of analyte diffusion and equilibrium analyte concentration.
