Microencapsulation Technology Microencapsulation technology refers to the use of natural or synthetic polymeric compound materials to make capsule wall shells (films) in which drugs (synthetic, semi-synthetic, biological products) are encapsulated in a capsule membrane and released at a controlled rate only under specific conditions. This technique has no effect on the original chemical properties of the drug, and the drug is released for therapeutic purposes by some external stimulation or slow release. Microcapsules generally have a diameter of 1 to 500 μm and a wall thickness of 0.5 to 150 μm. Microcapsules have the ability to improve and enhance the appearance of substances and their properties, store microscopic substances, delay and control release, and protect the core material from the environment, reduce toxicity, and shield it from odors.
