The study of microfluidics is used to replicate real-world chemical reactions or enable detection of the smallest amounts of substances. A perfect example of this is the “lab-on-a-chip” where chemical or biological reactions are observed on the microscale, thereby enhancing the efficiency and enabling the application in constricted/controlled conditions. Other examples include microfluidic chips which serve as sensors or “bio-chips” which are used for protein/DNA analysis or for diagnostics of microscopic blood samples.
