Abstract: How to achieve the interfacing between macro world and microchip is still one of the important topics in the research of microfluidic chips. In this paper, the recent progress in high-throughput microfluidic sample introduction techniques is described, mainly based on the work achieved in the authors’group. Various high-throughput microfluidic sample introduction systems in three modes including reservoir, flow-through cell and sampling probe based on microchips or capillaries are described. The developing prospects of high-throughput sample introduction techniques are also forecasted.
