Background Blood–brain barrier (BBB) is a crucial but dynamic structure that functions as a gatekeeper for the cen tral nervous system (CNS). Managing sufcient substances across the BBB is a major challenge, especially in the devel opment of therapeutics for CNS disorders. Methods To achieve an efcient, fast and safe strategy for BBB opening, an acoustofuidic transwell (AFT) was devel oped for reversible disruption of the BBB. The proposed AFT was consisted of a transwell insert where the BBB model was established, and a surface acoustic wave (SAW) transducer realized using open-source electronics based on printed circuit board techniques. Results In the AFT device, the SAW produced acousto-mechanical stimulations to the BBB model resulting in decreased transendothelial electrical resistance in a dose dependent manner, indicating the disruption of the BBB. Moreover, SAW stimulation enhanced transendothelial permeability to sodium fuorescein and FITC-dextran with vari ous molecular weight in the AFT device. Further study indicated BBB opening was mainly attributed to the apparent stretching of intercellular spaces. An in vivo study using a zebrafsh model demonstrated SAW exposure promoted penetration of sodium fuorescein to the CNS. Conclusions In summary, AFT efectively disrupts the BBB under the SAW stimulation, which is promising as a new drug delivery methodology for neurodegenerative diseases
