Micro-capsules represent a sub-category of microparticles that have the following structure:

- nucleus

- coating material

The nature of material of nucleus is different from the nature of material of outer layer. The size of a microparticle can vary from the smallest value of 50nm to 2000 mu m.

The material of the nucleus depends on the purpose that needs to be reached, while the material of coating is selected be with respect to its ability to form a film that is connected to the material of nucleus. The material of the coating must not develop reactions with the nucleus and it has to have chemical affinities with the material of nucleus. The material of the coating can be either hydrophobic polymers or hydrophilic polymers.

Microcapsules are small speres surrounded by an outer wall.  Reasons include protecting the core of the microcapsule, or simply controlling the rate at which the core exits the microcapsule.

Capsule and Slime are now collectively called as microcapsules. Negative staining by India ink is commonly employed for detection of capsule, in which capsule stands out as a halo. Sometimes no capsule can be detected with staining but on reacting the bacterium with the specific anti-capsule serum, an antigen-antibody reaction takes place (Quellung reaction). Such capsules are known as microcapsules.
