Phantom Membrane Microfluidic Cross-Flow Filtration Device for the Direct Optical Detection of Water Pollutants
(Elservier, 2017-11-06)The diffusion of autonomous sensing platforms capable of a remote large-scale surveillance of environmental water basins is currently limited by the cost and complexity of standard analytical methods. In order to create a ... -
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 ... -
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 ... -
Producing Omega-3 Polyunsaturated Fatty Acids: A Review of Sustainable Sources and Future Trends for the EPA and DHA Market
(MDPI, 2020-11-16)Omega-3 polyunsaturated fatty acids (Omega-3 PUFA) are recognized as being essential compounds for human nutrition and health. The human body generates only low levels of Omega-3 PUFA. Conventional sources of Omega-3 PUFA ... -
Production of Docosahexaenoic Acid and Odd-Chain Fatty Acids by Microalgae Schizochytrium limacinum Grown on Waste-Derived Volatile Fatty Acids
(MDPI, 2022-04-14)Heterotrophic microalgae are recognized as a source of bioactive compounds. However, there are still some drawbacks for their use at an industrial scale associated with the high cost of glucose, the main carbon source in ... -
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 ... -
Reviewing in situ analytical techniques used to research Martian geochemistry: From the Viking Project to the MMX future mission
(Elsevier, 2022-03-08)[EN] The study of space has always been a field of great interest and thus space missions are becoming more and more ambitious with time. Therefore, with the 50th anniversary of the first spacecraft to land on Mars, a ... -
Selective ultrasensitive optical fiber nanosensors based on plasmon resonance energy transfer
(American Chemical Society, 2020-04-03)The facet of optical fibers coated with nanostructures enable the development of ultraminiature and sensitive (bio)chemical sensors. The reported sensors until now lack of specificity and the fabrication methods offer poor ... -
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 ... -
