Encapsulation is a process of enclosing the substances within an inert material which protects from environment as well as
control drug release. Recently, two type of encapsulation has been performed in several research. Nanoencapsulation is
the coating of various substances within another material at sizes on the nano scale. Microencapsulation is similar to
nanoencapsulation aside from it involving larger particles and having been done for a greater period of time than
nanoencapsulation. Encapsulation is a new technology that has wide applications in pharmaceutical industries,
agrochemical, food industries and cosmetics. In this review, the difference between micro and nano encapsulation has been
explained. This article gives an overview of different methods and reason for encapsulation. The advantages and
disadvantages of micro and nano encapsulation technology were also clearly mentioned in this paper.
