Microfluidity refers to the movement of fluids and particles on a microscopic scale. Synonyms for this term include microflow, microhydrodynamics, and microfluidic transport. These synonyms are often used in the fields of microfabrication, chemical engineering, and biomedical engineering. Another related term is nanofluidics, which is the study of fluid behavior at the nanoscale. In recent years, microfluidic technology has been applied in various areas such as drug delivery, DNA analysis, and cell sorting. The development of this technology has led to improved diagnostic tools and better understanding of biological and chemical processes at the microscale.
