or cells which are of relatively large size may be entrapped in a maze of polymeric
molecules (a gel
). This procedure is called immobilization by inclusion. When the biocatalyst
is enclosed inside a semipermeable membrane
, usually approximately spherical, the method is known as encapsulation. In the process
of reticulation the primary biocatalyst
particles (individual enzyme molecules, cofactors
or individual cells) are covalently attached to each other by organic chains, into
a three-dimensional network
. The term grafting is also used in this context. Attachment
to the support by adsorption forces is called immobilization by adsorption.
