WHAT DOES OPSONISATION MEAN IN ENGLISH?
An opsonin, is any molecule that enhances phagocytosis by marking an antigen for an immune response. However, the term is usually used in reference to molecules that act as a binding enhancer for the process of phagocytosis, especially antibodies, which coat the negatively charged molecules on the membrane. Molecules that activate the complement system are also considered opsonins. Phagocytic cells do not have an Fc receptor for IgM, making IgM ineffective in assisting phagocytosis. However, IgM is extremely efficient at activating complement and is, therefore, considered an opsonin. Opsonins can also refer to molecules that target a cell for destruction through the action of natural killer cells.

This simple model shows that the opsonisation process makes the particle
surface more hydrophobic, and it is reasonable to assume that this is a major part
of the reason for phagocytosis. The fact that complement has been implicated as
