AC/DC millivoltage sensor by means of ITO-coated optical fibers: towards monitoring of biosignals
Aginaga Etxamendi, Concepción Isabel
; Socorro Leránoz, Abián Bentor 
; Fuentes Lorenzo, Omar ; Del Villar, Ignacio ; Corres Sanz, Jesús María ; Matías Maestro, Ignacio (IEEE, 2019)
Contribución a congreso / Biltzarrerako ekarpena 
This contribution shows the monitoring of AC and DC millivoltage signals by means of lossy mode resonances generated by Indium Tin Oxide (ITO) on optical fibers. Sensors were obtained by sputtering ITO thin-films onto 25 ... -
All fiber interferometer for ice detection
Arozarena Arana, Jesús Antonio; Socorro Leránoz, Abián Bentor ; Del Villar, Ignacio ; Díaz Lucas, Silvia ; Matías Maestro, Ignacio (Optica Publishing Group, 2018)
Contribución a congreso / Biltzarrerako ekarpena
This work presents an etched single-mode - multimode - single-mode structure that detects the solid-to-liquid change of state of the water due to an increased refractive index sensitivity within the 1.308 - 1.321 RIU range -
Fiber-based label-free D-dimer detection for early diagnosis of venous thromboembolism
Zubiate Orzanco, Pablo ; Urrutia Azcona, Aitor ; Ruiz Zamarreño, Carlos ; Fernández Irigoyen, Joaquín ; Giannetti, Ambra; Baldini, Francesco; Díaz Lucas, Silvia ; Matías Maestro, Ignacio ; Arregui San Martín, Francisco Javier ; Santamaría, Enrique; Del Villar, Ignacio ; Chiavaioli, Francesco (SPIE, 2020)
Contribución a congreso / Biltzarrerako ekarpena
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 ... -
Fiber-optic immunosensor based on lossy mode resonances induced by indium tin oxide thin-films
Socorro Leránoz, Abián Bentor ; Del Villar, Ignacio ; Corres Sanz, Jesús María ; Arregui San Martín, Francisco Javier ; Matías Maestro, Ignacio (IEEE, 2017)
Contribución a congreso / Biltzarrerako ekarpena
A novel immunosensor based on lossy mode resonances (LMRs) induced in optical fibers is developed in this contribution. Indium tin oxide (ITO) is sputtered on the optical substrate to generate an LMR in the transmission ... -
Lossy mode resonance enabling ultra-low detection limit for fibre-optic biosensors (INVITED)
Chiavaioli, Francesco; Giannetti, Ambra; Tombelli, Sara; Trono, Cosimo; Del Villar, Ignacio ; Matías Maestro, Ignacio ; Zubiate Orzanco, Pablo ; Ruiz Zamarreño, Carlos ; Arregui San Martín, Francisco Javier ; Baldini, Francesco (Springer, 2020)
