Popis: Layer-by-Layer coating technology is of great importance for many applications of microparticles whereby exposure of the particles to various reagents is needed. Mutual contamination of the reagents during this process is a key challenge, and this undesired effect should be avoided. Here we introduce a device that provides subsequent exposure of particles to various liquids and minimizes mixing of the liquids at the same time. The key element of the device is a rail (groove) at the bottom of a microfluidic channel. The rail forms an angle (between 0 and 90 degrees) and thus enables passive transport of particles through the intact co-flows of the different fluids. To avoid the undesirable effect of reagent stream mixing, internal walls are introduced to separate the different flows. Various designs of the proposed device are considered, and their performance is experimentally analyzed.
