What is Nanoparticles

Drug delivery is a procedure to transport drugs to an appropriate site for effective action, achieving the benefits of drugs. In the past few decades, nano-sized drug particles have attracted many researchers to develop an efficient drug delivery system. Microfluidic technology, for its ability to synthesize precise nanoparticles with uniform size, has emerged as a reliable technology for drug delivery. The microreactor has been established as a promising device due to its ability to provide intensive mixing in low-dimension microchannels having a high surface-to-volume ratio. It synthesizes drug particles with higher encapsulation efficiency and uniform particle size. The enhancement in the encapsulation efficiency results in the controlled release of drug particles at the appropriate site for effective medication. In addition, other applications of microreactors to synthesize various organic and inorganic nanoparticles are also discussed in this chapter.
