Journal ArticleDOI
Response time enhancement of pH sensing films by means of hydrophilic nanostructured coatings
TL;DR: In this article, the authors describe the improvement in response time of thin film optical fluorescent sensors for pH detection based on the 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS) pH-sensitive molecule.
Journal ArticleDOI
Simultaneous Measurement of Humidity and Temperature Based on an SiO $_{2}$ -Nanospheres Film Deposited on a Long-Period Grating In-Line With a Fiber Bragg Grating

TL;DR: In this article, a novel configuration able to measure simultaneously relative humidity and temperature is proposed, which is based on a long-period fiber grating (LPG) coated with silica nanospheres in-line with a fiber Bragg grating.
Journal ArticleDOI
A Lossy Mode Resonance optical sensor using silver nanoparticles-loaded films for monitoring human breathing
TL;DR: In this article, a human breathing sensor based on the in situ synthesis of silver nanoparticles (Ag-NPs) inside a polymeric coating previously deposited on an optical fiber core by means of the Layer-by-Layer self-assembly is presented.
Journal ArticleDOI
Optimization in nanocoated D-shaped optical fiber sensors
TL;DR: Nanocoated D-shaped optical fibers have been proven as effective sensors and the full width at half minimum (FWHM) of lossy mode resonance can be reduced by optimizing the nanocoating width, thickness and refractive index.
Journal ArticleDOI
Lossy mode resonance sensors based on lateral light incidence in nanocoated planar waveguides
TL;DR: The sensors presented here open up the path for the development of LMR-based chemical sensors, environmental sensors, biosensors, or even the generation of other optical phenomena with the deposition of multilayer structures, gratings or nanostructures, which is much easier in a planar waveguide than in an optical fibre.
