17. Conclusion
laccase appears a strong candidate for
biosensing applications, providing some
specific advantages over other enzymes
having;
The ability to catalyze electron-transfer reactions without
additional cofactors.
The ability to oxidize phenols and o,m,p-benzenediols in the
presence of molecular oxygen; and, good stability.
