Enzyme-Nanowire Mesocrystal Hybrid Materials with an Extremely High Biocatalytic Activity.

The laccase-Cu2O-nanowire mesocrystal hybrid materials were developed with a superior catalytic activity inspired by natural biocatalysis processes in living cells that highly resemble the metal ions activation and the well-organized spatial structure of the natural rough endoplasmic reticulum. The enzyme and nanobiocatalyst activities of the obtained hybrid material exhibited an approximate 10-fold and 2.2-fold increase than the free enzyme, surpassing the currently available nanobiocatalysts. The comprehensive catalytic performance of the hybrid materials has been further demonstrated using a prototype continuous-flow reactor for the bioremediation of 2,4-dichlorophenol-contaminated water, which showed a high degradation efficiency and remarkable reusability. These new highly efficient nanobiocatalysts are expected to be used for diverse applications in biotechnology, biosensing, and environmental remediation.
