The ever-growing demand for cost-effective and innocuous biocatalytic transformations has prompted the rational design and development of robust biocatalytic tools. Enzyme immobilization technology lies in the formation of cooperative interactions between the tailored surface of the support and the enzyme of choice, which result in the fabrication of tremendous biocatalytic tools with desirable properties, complying with the current demands even on an industrial level. Different nanoscale materi...

In the present study, we developed novel β-glucosidase-based nano-biocatalysts for the bioconversion of oleuropein to hydroxytyrosol. Using non-covalent or covalent immobilization approaches, β-glucosidases from almonds and Thermotoga maritima were attached for the first time on oxidized and non-oxidized porous carbon cuboids (PCC). Various methods were used for the characterization of the bio-nanoconjugates, such as Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscop...

Abstract This chapter deals with the use of functionalized derivatives of graphene oxide as nanoscaffolds for the immobilization and stabilization of laccase from Trametes versicolor. Covalent and noncovalent immobilization approaches are described, while a novel method for the development of laccase-based multilayer nanoassemblies is also presented. Various biochemical, spectroscopic, and microscopic techniques were applied to characterize the nanobiocatalytic systems in respect to their micros...
