Journal ArticleDOI
Reduction of surface roughness for optical quality microfluidic devices in PMMA and COC
I. R. G. Ogilvie,Vincent J. Sieben,Vincent J. Sieben,Cedric F.A. Floquet,Robert Zmijan,Matthew C. Mowlem,Hywel Morgan +6 more
TL;DR: In this article, a solvent vapour treatment is used to irreversibly bond microfluidic chips while simultaneously reducing the channel surface roughness, yielding optical grade (less than 15 nm) channel walls.
Journal ArticleDOI
Microfluidic colourimetric chemical analysis system: application to nitrite detection.
Vincent J. Sieben,Vincent J. Sieben,Cedric F.A. Floquet,I. R. G. Ogilvie,Matthew C. Mowlem,Hywel Morgan +5 more
TL;DR: In this article, a continuous flow, microfluidic absorption cell and detection system for detecting nitrite using the Griess reaction is described. But the system was used to detect nitrite, but it could equally be used to assay a range of different chemistries using colourimetric methods.
Journal ArticleDOI
An automated microfluidic colourimetric sensor applied in situ to determine nitrite concentration
Alexander Beaton,Alexander Beaton,Vincent J. Sieben,Vincent J. Sieben,Cedric F.A. Floquet,Edward M. Waugh,Samer K. Abi Kaed Bey,I. R. G. Ogilvie,I. R. G. Ogilvie,Matthew C. Mowlem,Hywel Morgan +10 more
TL;DR: A stand-alone sensor system with integrated sub-systems is demonstrated in this paper, which is capable of in situ reagent-based nutrient analysis and is based on a low cost optical detection method, together with an automated microfluidic delivery system that is able to detect nitrite with a limit of detection (LOD) of 15 nM.
Journal ArticleDOI
Chemically resistant microfluidic valves from Viton® membranes bonded to COC and PMMA.
I. R. G. Ogilvie,Vincent J. Sieben,Vincent J. Sieben,Barbara Cortese,Matthew C. Mowlem,Hywel Morgan +5 more
TL;DR: This work presents a reliable technique for irreversibly bonding chemically inert Viton® membranes to PMMA and COC substrates to produce microfluidic devices with integrated elastomeric structures and demonstrates and characterises on-chip pneumatic Viton®, microvalves on PMma and C OC substrates.
Journal ArticleDOI
Nanomolar detection with high sensitivity microfluidic absorption cells manufactured in tinted PMMA for chemical analysis.
Cedric F.A. Floquet,Vincent J. Sieben,Vincent J. Sieben,Ambra Milani,Etienne P. Joly,I. R. G. Ogilvie,I. R. G. Ogilvie,Hywel Morgan,Matthew C. Mowlem +8 more
TL;DR: A novel, cost effective and simple technique for the manufacture of high sensitivity absorption cells for microfluidic analytical systems that creates a pin-hole configuration over the length of the absorption cell, providing improved performances when used as an absorption cell compared to clear substrates.
