The enzyme-linked immunosorbent assay (ELISA) technique is based on the specific recognition ability of molecular structure an antigen (epitope) by antibody and likely most important diagnostic used today in bioscience. With this methodology, it possible to diagnose illness, allergies, alimentary fraud, even detect small molecules such as toxins, pesticides, heavy metals, etc. For reason, any procedures that improve detection limit, sensitivity or reduce analysis time could have impact...
In our previous work we demonstrated for the first time, to best of knowledge, experimental capability resonant nanopillars (R-NP) arrays as biochemical transducers. this Letter, provide evidence and suitability R-NP on a chip function label-free optical multiplexed biosensors. are based Si3N4/SiO2 Bragg reflectors with cavity SiO2. order demonstrate biosensing performance, were biofunctionalized by immobilization IgG antibodies acting bioreceptor. This was carried out through silanization...
We report the integration of an automated chemical optical sensing unit for parallel interrogation 12 BICELLs in a chip. The work was accomplished under European Project Enviguard (FP7-OCEAN-2013-614057) with aim demonstrating nano-biosensing in-situ detection various pollutants simultaneously oceanic waters. In this context, we designed chip based on resonant nanopillars (R-NPs) transducers organized layout twelve biophotonic cells (BICELLs). is interrogated reflection 12-channels...
Development of DNA and RNA biosensors the associated diagnostic tests have gained growing interest in recent years. In particular, short chains (around 25 oligonucleotides), known as micro RNAs, can be different stroke neurodegenerative diseases. Here, we present utilization highly sensitive fiber optic sensor based on Lossy Mode Resonance (LMR) for detection single strand complementary (ssDNA) to Huntington Disease (Hsa-miR-34b).
Superoxide dismutase enzymes (SODs) are an essential part of the first line cellular defense system against free radicals species. They catalyze dismutation superoxide into oxygen and hydrogen peroxide. Although several studies have examined attachment dismutases to nanoparticles nanostructures, never has been used a member Fe/MnSOD family. In this study, behavior plant origin FeSOD enzyme on three different nanopatterned surfaces was investigated as function covalent electrostatic binding....
Summary form only given. Spectrometers are widely used for scientific experiments in all different fields and real-time monitoring. In several setups it is necessary to measure a spectrum at positions over time [1], but with most spectrometers possible one time. For measuring two or more spectra simultaneously, which increases costs. the scope of EnviGuard project we have developed multichannel optical interrogator based on an integral field spectrometer that can capture up 12 channels parallel.

The iron superoxide dismutase (FeSOD) is a first barrier to defend photosynthetic organisms from radicals. Although it broadly present in plants and bacteria, FeSODs are absent animals. They belong the same phylogenic family as Mn-containing SODs, which also highly efficient at detoxifying In addition, SODs can react with peroxynitrite, FeSOD enzyme has already been used evaluate anti-nitrative capacity of plant antioxidants. Gold nanoparticles (AuNPs) have shown significantly improve...
We present a novel covalent functionalization of D-shape fiber biosensor based on Lossy Mode Resonances. IgG/anti-IgG model is applied to prove the regeneration union and thus re-usability sensor.
Hydrogen is gaining increasing attention in the recent years as an effective energy carrier for grid flexibilization and decarbonization of hard-to-abate sectors. Among different technologies under development power-to-hydrogen conversion, solid oxide electrolysis (SOE) outstands due to its high conversion efficiency, fuel flexibility (e.g., CO2 electrolysis) reversibility (i.e., same device can work both electrolyser cell). At Spanish National Renewable Energy Centre (CENER) we have...
Energy transition towards a net-zero emission scenario requires, primarily, significant increase on the renewable energy production capabilities. However, inherent intermittency of most common sources, added to limitations full electrification in some important hard-to-abate sectors (heavy-duty transport, aviation, steel industry...), implies also need developing reliable solutions for conversion and storage. Here, hydrogen is gaining more popularity recent years as an effective solution...
In recent works it has been demonstrated the suitability of using resonant nanopillars (R-NPs) as biochemical. this work shown capability R-NPs to behave label-free multiplexed biological sensors. Each R-NP is formed by silicon oxide (SiO2) and nitride (Si3N4) Bragg reflectors a central cavity SiO<sub>2</sub>, they are grouped into eight arrays called BICELLs, which distributed on single chip quartz substrate for multiplexing measurements. For sensing assessment was developed an immunoassay...
