The Laccase-like Property of GHK-Cu and Its Applications in Colorimetric Sensing of Phenolic Compounds

Laccase plays an important role in the detection and degradation of phenolic compounds, but it is limited by its cost and stability. In this study, the laccase-like property of copper peptide (GHK-Cu) has been revealed.
