Microfluidic Technology
微流控（Microfluidic）技术是一种基于（微）流体力学理论，在管线中实现样品制备与加工的技术。完·美的将微流体的理化模型与流体力学理论相结合，可实现样品的混合、乳化及分离纯化等功能。
Microfluidic technology is a kind of technology based on the theory of （Microfluidics）fluid mechanics, which can realize the sample preparation and processing in the pipeline. The perfect combination of the physical and chemical model of microfluidics and the theory of hydrodynamics can realized the functions of sample mixing, emulsification, separation and purification.
微流控技术将过程控制技术（Process Control Technology，PCT）与过程分析技术（Process Analytical Technology，PAT）相结合，可实现良好的在线样品制备技术（On-line Preparation Technology，OPT）。样品在连续化制备的过程中，工艺过程中参数完全可控，且具备良好重现性，所以较传统分步割裂式制备、分批次生产的方法来说更具有可放大性。
Microfluidic technology combines process control technology (PCT) with process analytical technology (PAT) to realize good on-line preparation technology (OPT). In the process of continuous preparation, the parameters in the process are completely controllable and have good reproducibility, so it can be better applied applied to production than traditional method of step-by-step split preparation and batch production.
可实现样品的初乳化、复乳化、粒径控制功能。

微流控制备系统通过制备泵和高压输送泵与微流控芯片相连接，A相和B相可按照一定的比例恒速的输送至芯片中进行混合，乳化。在微流控芯片中通过设计不同的流道结构，控制不同的速度，使得样品在微流控芯片中达到湍流、层流或雾化状态，可以实现样品的初乳化或复乳化的要求。
Microfluidic preparation system is connected with microfluidic chip by fabricating pump and high-pressure conveying pump. Phase A and phase B can be mixed and emulsified at constant speed in a certain proportion. In microfluidic chips, different runner structures are designed and different velocities are controlled to make the samples turbulent, laminar or atomized in the microfluidic chips, which can meet the requirements of pre-emulsification or re-emulsification.
制备好的样品通过高压泵输送至高压微流控芯片中，通过撞击力和剪切力来控制粒径，使其达到所需范围内。粒径最小可达到100nm以内，PDI至0.1以下。
The prepared samples were transported to the high pressure microfluidic chip by high-pressure pump, and the particle size was controlled by impact force and shear force to reach the required range. The smallest particle size can be less than 100nm, and PDI can be less than 0.1.
