Review the methods for crosslinking of (a) two amine derivatives; (b) amine and carboxyl derivatives; (c) alcohol and amine derivatives; (d) amine and thiol derivatives.

Suppose that you want to prepare an enzyme gel at a solid surface with no covalent bonding between the enzyme and the support. Design a suitable method and sketch the pertinent chemical reactions.
