On-demand generation and removal of alginate biocompatible microvalves for flow control in microfluidics
[EN] This paper describes, for the first time, the use of alginate hydrogels as miniaturised microvalves within microfluidic devices. These biocompatible and biodegradable microvalves are generated in situ and on demand, ...
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 ...
Microcantilever arrays functionalised with spiropyran photoactive moieties as systems to measure photo-induced surface stress changes
[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 ...
Fluidic flow delay by ionogel passive pumps in microfluidic paper-based analytical devices
[EN] A new concept for fluid flow manipulation in microfluidic paper-based analytical devices (m-PADs) is presented by introducing ionogel materials as passive pumps. m-PADs were fabricated using a new doubleside contact ...
