The encapsulation of materials is useful for a variety of settings, ranging from farming and construction to pharmaceutical. According to the requirements of each application, different processes and materials are used accordingly.
Fertilizers can be stored in a milli-sized sphere that releases its content slowly over a long period of time, avoiding the repeated addition of more fertilizer.
Pharmaceutical drugs that require slow absorption into the blood system could be nanoencapsulated according to requirements.
Construction materials that suffer from environmental exposure would be coated by nanoparticles in a microcapsule with a wide range of abilities: electrical and thermal insulation, and many more depending on desired properties.
