"Development of textile-based 3D constructs as novel electrofluidic sub" by Jawairia Umar Khan

The increased level of interest in the miniaturization of analytical devices has led to a focus on exploring new and inexpensive materials. This dissertation aims to investigate the combination of nascent textile-based microfluidics with electrophoretic control principles to develop the new groundbreaking textile-based electrofluidic systems for the direct and rapid characterization of analytes separated from complex mixtures and matrices. Capillary electrophoretic systems typically comprise inaccessible and fully enclosed micro-capillary or microchannels, with limited sample loading capacities and no direct access to the solutes within. Herein, we investigate the use of textile constructs as electrophoretic substrates to provide an open and surface-accessible separation platform. The techniques commonly utilized in capillary electrophoresis, including electrophoretic separation, isotachophoretic (ITP) preconcentration, and surface functionalization, were investigated using textile sub ....

"Melt polymer drawn single and multi-capillary fibre-based electroosmot" by Liang Wu, Syamak Farajikhah et al.

Microfluidic devices have been employed in micro-analytical systems and microelectronics using inexpensive, customisable fluid-handling automation at the microliter scale. Here we utilise a well-established fibre drawing technique, which offers a range of materials and capillary conformations, that can be utilized within microfluidic devices to control fluid movement via electroosmotic processes to produce a simple electroosmotic pump (EOP). Single capillary EOPs were fabricated from drawn PU capillary fibres with internal diameters ranging from 73 to 200 µm and were shown to be capable of actively transporting a buffer solution using an external driving electric potential. A maximum flow rate of 0.8 ± 0.1 μL/min was achieved for a 73 ± 2 µm diameter PU capillary fibre at an applied potential of 750 V/cm. This flow rate was successfully increased up to 5.3 ± 0.3 μL/min by drawing a multi-capillary array consisting of 4, 5 and 7 capillaries. ....
