Optical fiber vacuum sensor based on modal interferometer and PDMS coating
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
This work studies the behavior of polydimethylsiloxane (PDMS) as a transducer for optical vacuum pressure measurements. The optical structure chosen for this device is a modal interferometer achieved by splicing a coreless ...
Fiber-based label-free D-dimer detection for early diagnosis of venous thromboembolism
(SPIE, 2020)
info:eu-repo/semantics/conferenceObject,
D-dimer is a useful diagnostic biomarker for deep vein thrombosis or pulmonary embolism, collectively referred to as venous thromboembolism (VTE). The ability to detect in real-time the amount of D-dimer with a fast and ...
Lossy mode resonances biosensor for the detection of C-reactive protein
(Optica Publishing Group, 2016)
Contribución a congreso / Biltzarrerako ekarpena,
The fabrication and characterization of optical fiber biosensor based on Lossy Mode Resonances (LMR) to detect C-reactive protein (CRP) are presented. Indium tin oxide (ITO) coatings deposited on side-polished D-shaped ...
Monitoring the etching process in LPFGs towards development of highly sensitive sensors
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the monitoring of the etching process up to a diameter of 30 µm of two LPFG structures has been compared, one of them had initially 125 µm, whereas the second one had 80 µm. By tracking the wavelength shift ...
Detection of ethanol in human breath using optical fiber long period grating coated with metal-organic frameworks
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
An optical fiber sensor for ethanol detection in exhaled breath has been developed. It has been fabricated by functionalizing a Long Period Grating with a metal-organic framework, ZIF-8. The sensor’s response was tested ...
Title enhancement of the sensitivity of a volatile organic compounds MOF-sensor by means of its structure
(MDPI, 2017)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we experimentally compare several core structures of Microstructured Optical Fibers (MOFs) for low-finesse Fabry-Pérot (FP) sensors. These sensors are designed for Volatile Organic Compounds (VOCs) measurements. ...
Fiber-optic immunosensor based on lossy mode resonances induced by indium tin oxide thin-films
