Towards Smart Substrates for Controlling Micrometric Droplet Motion
In this contribution, we describe a novel approach to the problem of setting micrometric droplets in motion. First, this paper reviews the state-of-the-art methods to enable millimetric droplet motion, and investigates the scalability of the most promising techniques on the basis of preliminary experiments. Then, we propose a novel approach based on substrates with radial 3D pattern. In the poster, we will investigate this approach in further details using numerical models and systematic experiments.
