Fig. 2From: Open source board based acoustofluidic transwells for reversible disruption of the blood–brain barrier for therapeutic deliveryNumerical simulation of the acoustofluidic transwell (AFT). The SAW propagates on the surface of the substrate, inducing the leaky SAW in the transwell. The inset shows the leaky SAW coupling into the transwell insert, which produce pressure gradients in the mediumBack to article page
