Abstract

Disclosed is an apparatus, such as an acoustic for parallel profiling cell-matrix adhesion at single-cell level via the introduction of localized and uniform acoustic streaming into an open chamber microfluidic device. The adherent cells within the open chamber can be detached by the streaming-induced Stokes drag force, thereby allowing an accurate determination of the relevant forces and kinetics. The current device and method includes the digital regulation of acoustic streaming from a low level to high levels, and a large number of adherent cells can be ruptured from the substrate, and the particular adhesive forces and kinetics can be determined by the applied power. The acoustic device and the associated detachment technique can characterize the adhesion dynamics and kinetics of cells, such as mammalian cells and bacterial cells. And because fibronectin mimics cells and/or cell matrices, the acoustic device and the corresponding method has broad application in determining the force(s) required to detach cells from other types of cells and/or cell matrices.
