Microfluidics is the study and manipulation of small volumes of fluids, usually on the scale of microliters or nanoliters. The word is pronounced /ˌmaɪkrəʊfluːˈɪdɪks/. The "mi-" prefix comes from the Greek "mikros," meaning "small." The "cro-" is pronounced like "krah," reflecting the Greek letter rho (ρ) which sounds similar to "r" but with a trilled "r" sound. The "-fluidics" suffix comes from the Latin "fluidus," meaning "flowing." The word is commonly used in fields such as biotechnology, chemistry, and engineering.
Microfluidics refers to a field of research and technology that deals with the manipulation and control of small volumes of fluids on a micrometer or nanometer scale. It involves the study and development of systems that facilitate the precise handling of fluids, typically in small channels or devices known as microchannels or microfluidic chips.
This branch of science focuses on understanding the behavior and properties of fluids at the microscale, where capillary forces dominate over inertial forces. Microfluidic systems enable the control of fluid flow, mixing, and reactions, all within a miniaturized platform. By exploiting the unique characteristics of fluids at the microscale, microfluidics offers numerous benefits, including reduced reagent consumption, faster reaction times, and enhanced sensitivity.
Microfluidic devices often consist of interconnected channels and chambers that are etched or fabricated onto various materials, such as glass or polymers. These devices can facilitate a wide range of applications, including chemical and biochemical analysis, drug delivery systems, DNA sequencing, and point-of-care diagnostics.
The field of microfluidics has gained significant attention due to its potential for revolutionizing various industries and scientific disciplines. Its ability to precisely control and manipulate fluids at small scales offers tremendous opportunities for advancements in medical diagnostics, biotechnology, environmental monitoring, and material science. With ongoing research and development, microfluidics holds promise for the creation of highly sensitive and portable devices that could transform numerous fields and improve the quality of life.
The word "microfluidics" is derived from two different components.
The first component, "micro", comes from the Greek word "mikros", meaning "small" or "tiny". In modern usage, "micro" is used as a prefix to indicate something of small scale or size.
The second component, "fluidics", is derived from the word "fluid", which is derived from the Latin word "fluidus", meaning "liquid" or "flowing". "Fluidics" refers to the study or manipulation of fluids, particularly in small volumes or channels.
So, when these two components are combined, "microfluidics" refers to the science and technology of manipulating and controlling small amounts of fluids, typically at the microliter (10^-6 L) or nanoliter (10^-9 L) scale.
