It is the coating of a pathogen by complement to facilitate phagocytosis.
What is phagocytosis?
Phagocytosis is the process by which a cell uses its plasma membrane to engulf a large particle, giving rise to an internal compartment called the phagosome.
Opsonization refers to the process or molecular mechanism that uses opsonins to make a molecule (e.g. antigen) palatable to the phagocyte. For instance, opsonins (e.g. antibodies) bind to the surface of the bacterial cell.
Examples of opsonins are antibody molecules such as the IgM that are capable of activating the complement system to increase the susceptibility of antigens to phagocytosis.
Apart from phagocytosis, opsonization can also promote antibody-dependent cell-mediated cytotoxicity.
