Sensitivity improvement of a humidity sensor based on silica nanospheres on a long-period fiber grating
(MDPI, 2009)
Artículo / Artikulua,
This work addresses a new configuration that improves the sensitivity of a humidity sensor based on a long-period fiber grating coated with a SiO(2)-nanospheres film. An intermediate higher refractive index overlay, ...
Application of gold complexes in the development of sensors for volatile organic compounds
(World Gold Council, 2007)
Artículo / Artikulua,
Two different kinds of sensors have been developed by using the same kind of vapochromic complexes. The vapochromic materials [Au2Ag2(C6F5)(4)L-2](n) have different colours depending on the ligand L. These materials change, ...
Multicolor layer-by-layer films using weak polyelectrolyte assisted synthesis of silver nanoparticles
(Springer, 2013)
Artículo / Artikulua,
In the present study, we show that silver nanoparticles (AgNPs) with different shape, aggregation state and color (violet, green, orange) have been successfully incorporated into polyelectrolyte multilayer thin films using ...
Volatile organic compound optical fiber sensors: a review
(MDPI, 2006)
Artículo / Artikulua,
Volatile organic compound (VOC) detection is a topic of growing interest with applications in diverse fields, ranging from environmental uses to the food or chemical industries. Optical fiber VOC sensors offering new and ...
Development of an in-fiber nanocavity towards detection of volatile organic gases
(MDPI, 2006)
Artículo / Artikulua,
A fiber optic sensor for Volatile Organic Compounds (VOCs) detection has been developed and characterized for some organic gasses. The sensor is based on a novel vapochromic material, which is able to change its optical ...
Pyridine vapors detection by an optical fibre sensor
(MDPI, 2008)
Artículo / Artikulua,
An optical fibre sensor has been implemented towards pyridine vapors detection; to achieve this, a novel vapochromic material has been used, which, in solid state, suffers a change in colour from blue to pink-white in ...
High sensitive and selective C-reactive protein detection by means of lossy mode resonance based optical fiber devices
(Elsevier, 2017)
Artículo / Artikulua,

Artículo / Artikulua,
In this paper, a high sensitivity optical fiber pH sensor based on lossy mode resonance (LMR) generated
with transversal electric (TE) and transversal magnetic (TM) polarized light is presented. Poly(allylamine
hydrochloride) ...
Experimental study and sensing applications of polarization-dependent lossy mode resonances generated by D-shape coated optical fibers
(IEEE, 2015)
Artículo / Artikulua,
The fabrication and characterization of an optical fiber refractometer based on Lossy Mode Resonances (LMR) is presented. TiO2/ poly (sodium 4-styrenesulfonate) (PSS) coatings deposited on side-polished D-shaped optical ...
High sensitivity lossy-mode resonance refractometer using low refractive index PFA planar waveguide
(Elsevier, 2023)
Artículo / Artikulua,
In this work a new strategy to improve the sensitivity of refractometers based on lossy-mode resonances has been proved. The proximity of the PFA (tetrafluoroethylene-perfluoro polymer) substrate refractive index to that ...
