Inclusion immobilization

Inclusion immobilization is a process of immobilization in which a catalyst (be it a chemical catalyst, an enzyme , a dormant or an active cell ) is encased in a matrix so that it cannot be removed from it. At the same time, however, the matrix must offer enough free space for the supply and removal of starting materials and products by diffusion . The matrix envelope simultaneously increases the size of the catalyst particle so that it can be more easily separated from the reaction solution. Normally, several catalyst particles are combined in one inclusion property.

Microencapsulation

→ Main article : microencapsulation

The production of solid capsules is called microencapsulation. Possible inclusion matrices usually consist of organic polysaccharides (such as alginate , carrageenan , pectinate , gellan , chitosan , curdlan or cellulose derivatives ) or other polar polymers (such as polylactides , polylactide-co-glycolides , polyvinyl alcohol , silicone or polyurethane foams ).

In addition, it can also be included in lipid bilayers , which is referred to as a liposome.
