Several approaches have been reported for the immobilization of laccase such as entrapment into polymer support [11,12], absorption method [13], or covalent linkages [9, 14].
Though the process in solution has an obvious advantage that all the covalent bond formations formed are irreversible, the deficiency shows in a lot of aspects, such as hardness to direct monomers into a two-dimensional geometry, the enormously fast loss of solubility with increasing size of the polymer, and the increase in lateral extension strongly hampering in isotropic solution experiments.
