Conclusionlaccase 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.
