Chip-based waveguides for high-sensitivity biosensing and super-resolution imaging
In this review, we introduce some chip-based waveguide biosensing and imaging techniques, which significantly reduce the complexity of the entire system. These techniques use a well-confined evanescent field to interact with the surrounding materials and achieve high sensitivity sensing and high signal-to-noise ratio (SNR) super-resolution imaging. The fabrication process of these chips is simple and compatible with conventional semiconductor fabrication methods, allowing high-yield production. Combined with recently developed chip-based light sources, these techniques offer the possibility of biosensing and super-resolution imaging based on integrated circuits.
