Antibody Interactions

Optical biosensors based on one-dimensional photonic crystals sustaining Bloch surface waves are proposed to study antibody interactions and perform affinity studies. The presented approach utilizes two types of different antibodies anchored at the sensitive area of a photonic crystal-based biosensor. Such a strategy allows for creating two or more on-chip regions with different biochemical features as well as studying the binding kinetics of biomolecules in real time. In particular, the proposed detection system shows an estimated limit of detection for the target antibody (anti-human IgG) smaller than 0.19 nM (28 ng/mL), corresponding to a minimum surface mass coverage of 10.3 ng/cm2. Moreover, from the binding curves we successfully derived the equilibrium association and dissociation constants (KA = 7.5 × 107 M−1; KD = 13.26 nM) of the human IgG–anti-human IgG interaction.

A novel design of a silicon-on-insulator (SOI)-based resonator based on slot micro-ring and Bragg gratings is presented. The corrugated Bragg gratings are structured on both sides of slot micro-ring waveguides. The variation of the effective refractive index is detected by monitoring the shift of the spectral of the resonator. The transmission spectrum and field distribution of the sensor structures are simulated using finite-difference time-domain (FDTD) method. With the combination of the Bragg gratings, the measurement range of the sensor significantly increases without the restriction of a free spectral range (FSR). Our proposed sensor design provides a promising candidate for on-chip integration with other silicon photonic element.
