With advancements in technology in the area of drug delivery systems, the new concept of encapsulation of the nanoparticles has been looked upon with promising eyes by the scientists. Oftentimes earlier the use of nanoparticles for the target delivery of the active compound failed because the vehicle or the carrier nano particle got either destroyed or structurally and molecularly disturbed making it unfit to carry the drug or the active compound. In order to protect the carrier molecules from the environmental stress or damage the idea of encapsulation was proposed. Encapsulation is a technique in which the nanoparticle is coated with a protective and inert substance so that it is not damaged structurally or chemically on the way to the delivery. Nanoparticles find use in many fields such as the pharmaceutical sector, cosmetic industry as well as in many researches related to the biomedical field. These fields can have a breakthrough technology of encapsulation which can enhance the performance of various products associated with these industries. In this paper the process of microencapsulation of the nanoparticles will be discussed in detail. The paper will also include the advantages and disadvantages of microencapsulation of the nanoparticles. This review paper will give an account of different methods of encapsulation. Lastly the areas and fields where the encapsulated nanoparticles can be used will also be discussed in detail.
