Chip-scale microscopy imaging

Authors


Abstract

Chip-scale microscopy imaging platforms are pivotal for improving the efficiency of modern biomedical and bioscience experiments. Their integration with other lab-on-a-chip techniques would allow rapid, reliable and high-throughput sample analysis for applications in diverse disciplines. In typical chip-scale microscopy imaging platforms, the light path can be generalized to the following steps: photons leave the light source, interact with the sample and finally are detected by the sensor. Based on the light path of these platforms, the current review aims to provide some insights on design strategies for chip-scale microscopy. Specifically, we analyze current chip-scale microscopy approaches from three aspects: illumination design, sample manipulation and substrate/imager modification. We also discuss some opportunities for future developments of chip-scale microscopy, such as time multiplexed structured illumination and hydrodynamic focusing for high throughput sample manipulation.
