Reusable Ionogel-based Photo-actuators in a Lab-on-a-disc
(Elsevier, 2017-11-04)
This paper describes the design, fabrication and performance of a reusable ionogel-based photo-actuator, in-situ photopolymerised into a lab-on-a-disc microfluidic device, for flow control. The ionogel provides an effective ...
Photoswitchable Layer-by-layer Coatings Based on Photochromic Polynorbornenes Bearing Spiropyran Side Groups
(American Chemical Society, 2018-04-10)
Micro-capillaries, capable of light-regulated binding and qualitative detection of divalent metal ions in continuous flow, have been realised through functionalisation with spiropyran photochromic brush-type coatings. Upon ...
Micro-Capillary Coatings Based on Spiropyran Polymeric Brushes for Metal Ion Binding, Detection, and Release in Continuous Flow
(MDPI, 2018-04)
Micro-capillaries, capable of light-regulated binding and qualitative detection of divalent metal ions in continuous flow, have been realised through functionalisation with spiropyran photochromic brush-type coatings. Upon ...
Driving Flows in Microfluidic Paper-Based Analytical Devices with a Cholinium Based Poly Ionic Liquid Hydrogel
(Elsevier, 2018-01-31)
Paper microfluidics technology requires effective handling and control of fluids, and this remains as asignificant obstacle for their accessibility by end-users, inhibiting their transition from the laboratory intothe ...
Poly(ionic Liquid) Thermo-responsive Hydrogel Microfluidic Actuators
(2017-03-14)
tributylhexyl phosphonium sulfopropylacrylate (PSPA) poly(ionic liquid) (PILc) hydrogels as temperature controlled actuators in microfluidic devices. The hydrogel size is modulated by localised changes in its temperature ...
Adaptive coatings based on polyaniline for direct 2D observation of diffusion processes in microfluidic systems
(Elsevier, 2016-08)
[EN] Therefore the understanding and proper evaluation of the flow and mixing behaviour at microscale becomes a very important issue. In this study, the diffusion behaviour of two reacting solutions of HCI and NaOH were ...
Microcantilever arrays functionalised with spiropyran photoactive moieties as systems to measure photo-induced surface stress changes
(Elsevier, 2016-12)
[EN] Herein we investigate the feasibility of detecting photo-induced surface stress changes using the deflection response of cantilevers. For this purpose, silicon microcantilevers have been functionalised with spiropyran ...
Porous self-protonating spiropyran-based NIPAAm gels with improved reswelling kinetics
(Springer, 2016-02)
[EN] This study focuses on improving the speed ofactuation of poly(N-isopropylacrylamide)-based photoresponsive gels containing copolymerised spiropyran as the photoswitch and acrylic acid as the proton source. The improvement ...
