Immobilization and purification of enzymes are usual requirements for their industrial use. Both purification and immobilization have a common factor: they use a solid activated support. Using a support for enzyme purification means having mild conditions for enzyme release and a selective enzyme-support interaction is interesting. Using a support for immobilization, enzyme desorption is a problem. The improvement of enzyme features via immobilization is a usual objective (e.g., stability, selectivity) Thus, a support designed for enzyme purification and a support designed for enzyme immobilization may differ significantly. In this review, we will try to focus the attention on the requirements of a support surface to produce the desired objectives. The ideal physical properties of the matrix, the properties of the introduced reactive groups, the best surface activation degree to reach the desired objective, and the properties of the reactive groups will be discussed.

Keywords:Enzyme stabilization, Enzyme immobilization, Enzyme purification, superficial density of reactive groups, multipoint attachment, one point attachment.
