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