Planar photonic crystal waveguide biosensor
We present protein detection using a planar photonic crystal waveguide sensor. Experimental results of refractive index measurements show good agreement with simulations. The sensor has been used for protein detection and showed successful detection with excellent signal to noise ratio of proteins with concentrations around 10 μg/ml (0.15μMolar). Introduction In the past 20 years, the research...
متن کاملSensitivity of the acoustic waveguide biosensor to protein binding as a function of the waveguide properties.
The aim of this work is to study the effect of operating frequency, piezoelectric substrate and waveguide layer thickness on the sensitivity of the acoustic waveguide sensor during the specific binding of an antibody by a protein. Shear horizontal (SH) wave devices consisting of (a) a LiTaO3 substrate operating at 104 MHz, (b) a quartz substrate operating at 108 MHz and (c) a quartz substrate o...
متن کاملGuided mode biosensor based on grating coupled porous silicon waveguide.
Porous silicon waveguide biosensors that utilize grating couplers etched directly into porous silicon are demonstrated for improved molecular detection capabilities. Molecules are infiltrated through the grating couplers into the waveguide where they can interact with a guided waveguide mode. Hybridization of nucleic acids inside the waveguide is shown to significantly perturb the wave vector o...
متن کاملResonant waveguide grating biosensor for living cell sensing.
This article presents theoretical analysis and experimental data for the use of resonant waveguide grating (RWG) biosensors to characterize stimulation-mediated cell responses including signaling. The biosensor is capable of detecting redistribution of cellular contents in both directions that are perpendicular and parallel to the sensor surface. This capability relies on online monitoring cell...
متن کاملSelf-referenced spectroscopy using plasmon waveguide resonance biosensor
A plasmon waveguide resonance (PWR) sensor is designed, fabricated, and tested for self-referenced biosensing. The PWR sensor is able to support two different polarizations, TM and TE. The TM polarization has a large sensitivity to variations in the background refractive index while the TE polarization is more sensitive to the surface properties. The ability of the PWR sensor to simultaneously ...
