Microencapsulation: Application and Recent Advances- A Review

Microencapsulation is the process of encapsulating one material entirely within another on a very small scale, resulting in capsules ranging in size from less than 1-100. The encapsulation efficiency of the microcapsule is affected by various aspects such as polymer concentration, polymer solubility in solvent, solvent removal rate, organic solvent solubility in water, and so on. There are numerous strategies for achieving microencapsulation. The objective of microencapsulation of substances may be to restrict the core content within capsule walls for a certain period of time. Core materials, on the other hand, can be encapsulated so that the core material is released gradually through the capsule walls, a process called as controlled release or diffusion, or when an external condition activates the capsule walls
