T
he development of novel nano biocatalytic systems through the immobilization of enzymes on nanoscale materials has
attracted much scientific interest and their potential use for applications in various industrial fields has been widely
recognized. Among the different types of nanomaterials applied for this purpose, carbon-based materials, such as graphene
oxide (GO), the oxidized derivative of graphene, and hierarchical porous carbons (HPC), which possess a multimodal pore
size distribution of micro-, meso-, and macropores, have been used for enzyme immobilization. On the other hand, magnetic
nanoparticles due to their high surface area, large surface-to-volume ratio and easy separation under external magnetic fields
have been broadly utilized as carriers for enzyme immobilization. The functionalization of magnetic nanoparticles with carbon-
based nanomaterials has recently attracted great interest as the resulting hybrid nanomaterials combine the properties of both
building blocks. In the present study, we investigate the use of hybrid nanomaterials of magnetic iron nanoparticles with GO
or HPC as nano supports for the immobilization of cellulolytic enzymes which could be applied to generate glucose feedstock
using lignocellulosic biomass. The aim of this work focuses on the investigation of the effect of structural characteristics of
hybrid GO and HPC magnetic nanoparticles on the catalytic behavior (activity, thermo stability and operational stability) of
cellulolytic enzymes.

Biography
A Papadopoulou studied biology at the University of Ioannina, Greece. She has completed her Master of Science degree in Department of Chemistry at University
of Ioannina. She has completed her PhD working in the area of Biocatalysis and Enzyme Technology in 2017. Her research focuses on the development of
immobilized biocatalytic systems based on the use of solid supports such as nano matrices for the production of biofuels, high-added value products with prospects
in food and pharmaceutical industry or for pollutants degradation.
