Schematic and working principle of the taSSAW based particle-coating device. (a) 3D illustration of the five-inlet, two-outlet PDMS microchannel and tilted IDTs on lithium niobate (LiNbO3) substrate. Not to scale. (b) Particles entering the device from the bottom inlet are pushed to the pressure nodes by the acoustic radiation force. While the particles migrating across the microchannel, they are coated with the red stream, washed, coated with the blue stream, and leave the device in the final buffer stream.
