The encapsulation process involves several steps: 1. Preparation of the Core Material: The material to be encapsulated is prepared in the desired form (liquid, solid, or gas). 2. Selection of Encapsulating Material: A suitable material (polymer, lipid, etc.) is chosen based on the requirements of the application. 3. Encapsulation Process: Various techniques like emulsification, coacervation, spray drying, and layer-by-layer assembly are used to encapsulate the core material. 4. Characterization: The encapsulated nanoparticles are characterized using techniques such as Dynamic Light Scattering (DLS), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM) to ensure the desired properties are achieved.
