Slow-release is a strategy in material science in which a chemical compound is introduced into a system at a reduced speed. Slow-release is applied in fertilizers, pesticides and drugs. Getting a chemical at a certain spot whether it is on a plant or inside the human body comes at a cost because of the spraying effort and pill consumption. If the desired effect is to last, administering the chemical has to be repeated over and over again. Supplying a large single dose reduces that frequency but is not always an option because the large dose is toxic or has adverse side effects compared to a small dose. Slow-release combines the beneficial effects of applying a single large dose distributed over a long time in small quantities. Slow release systems work by reducing the diffusion of a chemical into the system. The practical technology behind slow-release can be found in Micro-encapsulation or inclusion compounds.
