    • A system for particle manipulation and sorting based on structural acoustic field comprises a sample holder, an ultrasound transmission device and an artificial structure, the sample holder is used to place particles to be sorted, the ultrasound transmission device is used to transmit ultrasound wave, the artificial structure is periodic structure used to modulate acoustic field to produce stronger acoustic radiation force and sort the particles to be sorted. And there is a method for particle manipulation and sorting based on structural acoustic field. Due to the sample holder, the ultrasound transmission device and the artificial structure, plurality of particles could be placed on the sample holder simultaneously, the artificial structure is used to modulate the acoustic field to produce stronger acoustic radiation force, trapping the specific particles under the lower surface of the artificial structure at the same time, realizing rapid, batch sorting and increasing the efficiency.
    • 基于结构声场的粒子处理和分选系统包括样品架,超声波传输装置和人造结构,样品架用于放置待分选的颗粒,超声波传输装置用于传输超声波, 人造结构是用于调制声场以产生更强的声辐射力并对待分类的颗粒进行分类的周期性结构。 还有一种基于结构声场的粒子操纵和排序方法。 由于样品架,超声波传输装置和人造结构,多个颗粒可以同时放置在样品架上,人造结构用于调制声场以产生更强的声辐射力,将特定颗粒捕获在 人造结构的下表面同时实现快速,批量分选和提高效率。
