Journal ArticleDOI
Passivated aluminum nanohole arrays for label-free biosensing applications.
Víctor Canalejas-Tejero,Sonia Herranz,Alyssa Bellingham,María C. Moreno-Bondi,Carlos Angulo Barrios +4 more
TL;DR: An aluminum surface passivation treatment based on oxygen plasma is developed in order to circumvent the undesired effects of oxidation and corrosion usually found in aluminum-based biosensors.

Waveguide structure for guiding light in low-index material
TL;DR: A high-index-contrast waveguide structure material used to guide light through a low-refractive-index material is described in this paper, where the waveguide structures are capable of guiding and confining light in such a way that very high optical intensity is obtained in a small cross-sectional area or gap filled with any material with sufficiently low refractive index, relative to the remainder of the structure.
Journal ArticleDOI
High-performance all-optical silicon microswitch
TL;DR: In this paper, an integrated micron-size all-optical Si switch capable of 94.7 GHz operation frequency is presented, which consists of a microring resonator formed by Si/SiO/sub 2/ slot-waveguides with a low-index nonlinear optical material in the slot region.
Journal ArticleDOI
Label-free biosensing by means of periodic lattices of high aspect ratio SU-8 nano-pillars
Miguel Holgado,Carlos Angulo Barrios,Francisco Ortega,Francisco J. Sanza,Rafael Casquel,M.F. Laguna,María-José Bañuls,D. López-Romero,R. Puchades,Ángel Maquieira +9 more
TL;DR: Biophotonic sensing arrays of 60x60 microm(2) made of periodic lattices of high aspect ratio SU-8 nano-pillars are developed in order to demonstrate their capability for label-free molecule detection, as well as the sensitivity enhancement in comparison with a single layer ofSU-8.
Journal ArticleDOI
Selective chemical modification of silicon nitride/silicon oxide nanostructures to develop label-free biosensors.
María-José Bañuls,Victoria González-Pedro,Carlos Angulo Barrios,Rosa Puchades,Ángel Maquieira +4 more
TL;DR: The effectiveness of the novel selective surface modification procedure is supported by comparing experimental and numerical calculations of the optical performance of a label-free optical ring resonator based on Si(3)N(4)/SiO(2) slot-waveguides.
