Figure Lengend Snippet: Novel microfabrication techniques combined with creativity enable the production of different microfluidic tools that, in turn, facilitate the development of novel experimental paradigms to be used with small multicellular model organisms. Microfluidics empower researchers with tremendous control over sample stimulation while also enabling precise manipulation of samples, and being compatible with high-resolution live imaging. The potential of these microtechnologies is accelerating as they are integrated with additional technologies, become more accessible, and are designed to be multifunctional.
