Low‑cost origami fabrication of 3D self‑aligned hybrid microfluidic structures
(Springer, 2016-08)
[EN] 3D microfluidic device fabrication methods are normally quite expensive and tedious. In this paper, we present an easy and cheap alternative wherein thin cyclic olefin polymer (COP) sheets and pressure sensitive ...
On-demand generation and removal of alginate biocompatible microvalves for flow control in microfluidics
(Elsevier, 2016-10-29)
[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, ...
Sensing parasites: proteomic and advanced bio-detection alternatives
(Elsevier, 2016-03-16)
[EN] Parasitic diseases have a great impact in human and animal health. The gold standard for the diagnosis of the majority of parasitic infections is still conventional microscopy, which presents important limitations in ...
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 ...
Fluidic flow delay by ionogel passive pumps in microfluidic paper-based analytical devices
(Elsevier, 2016-10-05)
[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 ...
Multispectroscopic and Isotopic Ratio Analysis To Characterize the Inorganic Binder Used on Pompeian Pink and Purple Lake Pigments
(ACS Publications, 2016-05-18)
Because of the fact that pigments are not ubiquitous in the archeological record, the application of noninvasive analytical methods is a necessity. In this work, pink and purple lake pigments recovered from the excavations ...
Portable and Raman imaging usefulness to detect decaying on mortars from Punta Begoña Galleries (Getxo, North of Spain)
(Wiley, 2016-12)
Punta Begoña Galleries were built in 1918 in Getxo (Basque Country, North of Spain) but were abandoned in 1960. Nowadays, their conservation state is very poor. In this work, portable Raman spectroscopy was applied to ...
Understanding the behavior of stimuli-response ionogels for microfluidic applications
(Elsevier, 2016)
Electrochemical Impedance Spectroscopy (EIS) studies of two different ionogels (IOs) are performed using gold interdigitated electrodes (Au-IDEs). Poly(N isopropylacrylamide) (pNIPAAM) is polymerized in the presence of two ...
