Microfluidic refers to a technology that deals with manipulating small amounts of fluids in microscale devices. It involves the handling, storage, and processing of tiny volumes of liquids, typically measured in microliters or nanoliters. Microfluidics is used in various applications such as chemical analysis, biotechnology, pharmaceuticals, and medical diagnostics. The technology allows for precise control over fluid movement and mixing, making it possible to perform complex experiments with minimal amounts of reagents and samples.
