Definition: The term "unilamellar" is a technical term used in the field of microfluidics and nanofluidics. It refers to a type of device that consists of two separate layers, each with a single layer of lamella (a thin film) between them. In unilamellar devices, the lamella is typically made from a material such as glass or plastic, and it has a very low surface tension, which allows for fluid flow through the device. This can
