The surface area of a photonic crystal biosensor is greatly enhanced through the incorporation of a porous TiO2 film possessing the structure of nanorods into the device. The film is deposited by the glancing angle deposition technique in an e-beam evaporation system. The sensitivity of high surface area sensors is compared with sensors without the high surface area coating. Results for detecti...

We theoretically and experimentally demonstrate an ultrasensitive two-dimensional photonic crystal microcavity biosensor. The device is fabricated on a silicon-on-insulator wafer and operates near its resonance at 1.58 microm. Coating the sensor internal surface with proteins of different sizes produces a different amount of resonance redshift. The present device can detect a molecule monolayer...
This paper reports the design, fabrication and validation of a microfluidic well plate for combinatorial screening applications. Each well within the array is comprised of two 200 picoliter compartments that each contain a photonic crystal biosensor to enable the on-chip, in situ detection of (bio-) molecular binding events. This microfluidic chip utilizes arrays of Actuate-to-Open valves to is...
Design and process development of a photonic crystal polymer biosensor for point of care diagnostics
In this work, we report advances in the fabrication and anticipated performance of a polymer biosensor photonic chip developed in the European Union project P3SENS (FP7-ICT4-248304). Due to the low cost requirements of point-ofcare applications, the photonic chip is fabricated from nanocomposite polymeric materials, using highly scalable nanoimprint-lithography (NIL). A suitable microfluidic st...
Inhibitors and activators of protein-protein interactions are valuable as biological probes and medicinal agents but are often difficult to identify. Herein we describe a high-throughput assay, based upon photonic crystal (PC) biosensors, for the identification of modulators of protein-protein interactions. Through the use of a d-biotin-tris-NTA (BTN) hybrid compound, any His6-tagged protein ca...
Abstract In this paper, a novel design of photonic crystal fiber (PCF) biosensor based on surface plasmon resonance (SPR) is introduced and analyzed for cancer cell detection. The full vectorial finite element method (FVFEM) used throughout the numerical analysis suggested biosensor. reported PCF has V-shaped that coated with ZrN as plasmonic material. A coupling occurs between core guided mode...
A refractive-index biosensor is modeled using a photonic crystal ring resonator. The proposed sensor possesses high selectivity and quality-factor against different bacterial water samples. introduction of the circular rim in resonator structure responsible for sharp resonance that makes it suitable detecting impurities. sufficiently separated resonant peak samples offers possibility highly sel...
in this paper, using annular resonator we have designed an adding and dropping filter light based ontwo-dimensional photonic crystals. the shape of ring resonator filter adding and dropping that wehave proposed is race track. this filter has a hexagonal lattice structure of silicon bars withrefractive index 3/46 that is located in the context of air with refractive index 1. transmissionefficien...
