Droplet-based microfluidics which involves the generation of producing high mono-dispersity drops offers a platform for miniaturizing LbL technique by imparting benefits of time and reagent reduction. In the classical lay-by-layer technique, polyelectrolyte multi-layer capsules are fabricated by alternatively deposited charged polyelectrolytes onto an oppositely charged colloidal template followed by dissolved the template which is high consuming. We present a novel deposition method by designing a new microfluidic coating device which utilizes �Z� shape channel to guide discrete templates. Similar to the game of pinball in which the templates guided and diverted to the downstream direction smoothly by repeated unit rows of fabricated channels. Shorter fabrication time of multilayer capsules can be achieved regarding to the number of layer in this kind of microfluidic device.
