Porous self-protonating spiropyran-based NIPAAm gels with improved reswelling kinetics
[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 ...
Adaptive coatings based on polyaniline for direct 2D observation of diffusion processes in microfluidic systems
[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 ...
Reusable Ionogel-based Photo-actuators in a Lab-on-a-disc
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 ...
Poly(ionic Liquid) Thermo-responsive Hydrogel Microfluidic Actuators
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 ...
Driving Flows in Microfluidic Paper-Based Analytical Devices with a Cholinium Based Poly Ionic Liquid Hydrogel
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 ...
