Porous silicon seems to be an appropriate material platform for the development of high-
sensitivity and low-cost optical sensors, as their porous nature increases the interaction with …

We report on the demonstration of real-time refractive index sensing within 60 μm thick free-
standing macroporous alumina membranes with pore diameters of 200 nm. The free …

Encapsulating polymer materials into metal–organic frameworks (MOFs) is an effective
strategy to enhance the optical anisotropy of polymers, by aligning the polymer chains within …

We report on a photonic sensor with an ultralow limit of detection (LoD) based on a phase
interrogation readout scheme together with an anisotropic porous silicon (PSi) membrane …

We report the first demonstration of real-time biosensing in free standing macroporous
alumina membranes. The membranes with their 200 nm diameter pores are ideal …

We present measurements and analysis of the reflection spectrum of white light from a
highly birefringent porous silicon layer at different polarization states. We report an …

We interrogate a sensor based on a highly birefringent film, irradiated by an incident beam
whose polarization is oriented 45° with respect to the normal film axes. The reflected …

Biosensors are analytical devices used for the detection of a biological analyte. They consist
of a biological receptor molecule combined with a physical or physiochemical transduction …

La salud y el bienestar siempre han sido el centro de atención de muchas instituciones de
investigación y empresas de todo el mundo. Esto llevó a la tecnología a desarrollarse en los …

For ring resonator based sensors, volumetric limits of detection (LoD) of 5× 10− 6 RIU and
8.3× 10− 6 RIU (refractive index units) for sensitivities of 246nm/RIU and 2169nm/RIU were …
