This review mainly focuseson the concept of biomimetic microfluidics to improve the properties of microfluidic systemsfor breaking through the bottlenecks of the current microfluidic devices, such as antifoulingsmart, anddynamic response insidethe microchannelsunder different environments. In addition, here we show the current research progress of biomimetic microfluidic systems in applications related to antifouling and smart devices, and biomedical research. The review discusses both physical theories and critical technologies in the biomimetic microfluidics, from biomimetic design to real-world applications, so as to offer new ideas for the design and application of smart microfluidics, and the authors hope this review will inspire the active interest of many scientists in the area of the development and application of soft matter, and multi-functional and smart biomimetic devices.国家自然科学基金(批准号:21673197);国家自然科学基金(批准号:U1505243)资助的课题;; 高等学校学科创新引智计划(批准号:B16029)~
