A Nanoparticle is defined as a particle between 1 and 100 nanometres in size. Nanoparticle synthesis research is currently an area of intense scientific interest due to a wide variety of potential applications in biomedical, optical and electronic fields.
In the biomedical field two classes of nano particle synthesis are having increased applications in in-vivo and vitro biological applications, these are Quantum dots and metal colloids. In recent years chemists have been moving away from traditional batch based processes towards flow processing. For both quantum dots and metal colloid formation, microﬂuidic synthesis has been shown to be superior to traditional batch methods for producing high quality, monodisperse particles due to the ability to maintain ﬁne control of all reaction variables including reactant concentration, mixing, timing of reagent addition, and temperature.
