Particle separation has been extensively studied in recent years in a wide range of sciences, especially in the field of medicine and biotechnology. On the other hand, the topic has been considered in the context of interdisciplinary research; hence, many experiments have been carried out in this field. Particle separation is used to track particles during the drug-delivery process, the direction of the droplets in a specified path, etc. Both numerical and experimental methods have been used for separating and sorting different particles. Particle separation is performed using both active and passive techniques. In the present work, various passive techniques of particle separation are explained and compared to evaluate the separation efficiency, throughput rate, and clogging in microfluidic devices. The present paper focuses on the investigations conducted in particle separation between 2015 and 2020.

近年来，在许多科学领域，尤其是在医学和生物技术领域，对颗粒分离进行了广泛的研究。另一方面，该主题是在跨学科研究的背景下考虑的。因此，在该领域已经进行了许多实验。颗粒分离用于在药物输送过程中跟踪颗粒，指定路径中的液滴方向等。数值和实验方法均已用于分离和分类不同的颗粒。使用主动和被动技术都可以执行粒子分离。在当前的工作中，解释并比较了各种被动的粒子分离技术，以评估分离效率，吞吐速率和微流体装置中的堵塞。
