An antibacterial coating based on a polymer/sol-gel hybrid matrix loaded with silver nanoparticles
Rivero Fuente, Pedro J.
; Urrutia Azcona, Aitor ; Goicoechea Fernández, Javier ; Ruiz Zamarreño, Carlos ; Arregui San Martín, Francisco Javier ; Matías Maestro, Ignacio (Springer, 2011)
Artículo / Artikulua 
In this work a novel antibacterial surface composed of an organic-inorganic hybrid matrix of tetraorthosilicate and a polyelectrolyte is presented. A precursor solution of tetraethoxysilane (TEOS) and poly(acrylic acid ... -
Continuous liquid-level sensor based on a long-period grating and microwave photonics filtering techniques
Ricchiuti, Amelia L.; Barrera, D.; Urrutia Azcona, Aitor ; Goicoechea Fernández, Javier ; Arregui San Martín, Francisco Javier (IEEE, 2016)
Artículo / Artikulua
A fiber optic liquid-level sensor based on a long period grating (LPG) is proposed and experimentally validated. The principle of operation is based on a technique used to analyze microwave photonics filters. A 4-cm-long ... -
Effect of both protective and reducing agents in the synthesis of multicolor silver nanoparticles
Rivero Fuente, Pedro J. ; Goicoechea Fernández, Javier ; Urrutia Azcona, Aitor ; Arregui San Martín, Francisco Javier (Springer, 2013)
Artículo / Artikulua
In this paper, the influence of variable molar ratios between reducing and loading agents (1:100, 1:50, 1:20, 1:10, 1:5, 1:2, 1:1, 2:1) and between protective and loading agents (0.3:1, 0.75:1, 1.5:1, 3:1, 7.5:1, 30:1, ... -
Micro and nanostructured materials for the development of optical fibre sensors

The measurement of chemical and biomedical parameters can take advantage of the features exclusively offered by optical fibre: passive nature, electromagnetic immunity and chemical stability are some of the most relevant ... -
Multicolor layer-by-layer films using weak polyelectrolyte assisted synthesis of silver nanoparticles
Rivero Fuente, Pedro J. ; Goicoechea Fernández, Javier ; Urrutia Azcona, Aitor ; Matías Maestro, Ignacio ; Arregui San Martín, Francisco Javier (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 ... -
Nanomaterials for functional textiles and fibers
Rivero Fuente, Pedro J. ; Urrutia Azcona, Aitor ; Goicoechea Fernández, Javier ; Arregui San Martín, Francisco Javier (Springer US, 2015)
Artículo / Artikulua
Nanoparticles are very interesting because of their surface properties, different from bulk materials. Such properties make possible to endow ordinary products with new functionalities. Their relatively low cost with ... -
Novel highly sensitive protein sensors based on tapered optical fibres modified with Au-based nanocoatings
Urrutia Azcona, Aitor ; Bojan, Kartheka; Marques, Leonel; Mullaney, Kevin; Goicoechea Fernández, Javier ; James, Stephen; Clark, Matt; Tatam, Ralph; Korposh, Sergiy (Hindawi Publishing Corporation, 2016)
Artículo / Artikulua
Novel protein sensors based on tapered optical fibres modified with Au coatings deposited using two different procedures are proposed. Au-based coatings are deposited onto a nonadiabatic tapered optical fibre using (i) a ... -
Optical fiber sensors based on nanoparticle-embedded coatings
Urrutia Azcona, Aitor ; Goicoechea Fernández, Javier ; Arregui San Martín, Francisco Javier (Hindawi Publishing Corporation, 2015)
Artículo / Artikulua
The use of nanoparticles (NPs) in scientific applications has attracted the attention of many researchers in the last few years. The use of NPs can help researchers to tune the physical characteristics of the sensing coating ... -
