We describe a signal amplified biosensor based on self-assembled optical diffraction grating of a Fresnel zone plate structure. Diffracted light rays passed through gratings are interfered constructively at the focal point, resulting in the enhanced signal amplification without sacrificing signal-to-noise ratio (SNR).
