Abstract

A method of trapping particles, in a sample of a disperse liquid, having a non-zero acoustic contrast factor relative to a suspending liquid, comprising: i. providing an acoustofluidic device comprising a substrate in which a cavity is formed, the cavity being at least partially filled with a trapping matrix comprising or consisting of a material having a non-zero acoustic contrast factor, the cavity having an inlet for introducing the sample into the cavity, and an ultrasound transducer in acoustic contact with the substrate, ii. Introducing the sample into the cavity so the sample perfuses the trapping matrix, and iii. actuating the ultrasound transducer at an actuation frequency which does not correspond to a resonance of the cavity filled with the sample of disperse liquid, and couples an acoustic wave into the substrate. A system is also provided.
