Liquid-core low-refractive-index-contrast Bragg fiber sensor [PDF]
, 2011 We propose and experimentally demonstrate a low-refractive-index-contrast hollow-core Bragg fiber sensor for liquid analyte refractive index detection. The sensor operates using a resonant sensing principle- when the refractive index of a liquid analyte ...

Dual refractive index and viscosity sensing using polymeric nanofibers optical structures [PDF]
, 2019 Porous materials have demonstrated to be ideal candidates for the creation of optical sensors with very high sensitivities. This is due both to the possibility of infiltrating the target substances into them and to their notable surface-to-volume ratio ...

High Sensitivity Refractive Index Sensor by D-Shaped Fibers and Titanium Dioxide Nanofilm
Advances in Condensed Matter Physics, 2018 This paper presents a high sensitivity liquid refractive index (RI) sensor based on lossy mode resonance (LMR) effect. The D-shaped fibers coated with nanosized titanium dioxide (TiO2) thin film as a sensing head were submerged into different refractive ...

Refractive index sensing using Fluorescence Lifetime Imaging (FLIM)
Journal of Physics: Conference Series, 2006 The average fluorescence lifetime of GFP in solution is a function of the refractive index of its environment. Here, we demonstrate that this also appears to be the case for GFP-tagged proteins in cells. Using TCSPC-based FLIM with a scanning confocal microscope, we image GFP-tagged proteins in fixed cells in different media.

Comparison between Vernier-cascade and MZI as transducer for biosensing with on-chip spectral filter [PDF]
, 2017 The Mach-Zehnder interferometer (MZI) and the Vernier-cascade are highly responsive photonic sensors with large design freedom. They are therefore very suitable for interrogation through a broadband source and an on-chip spectral filter, a sensing scheme
