Enzymes are proteins specialized in catalyzing biological reactions. However, factors such as cost and operational limitations could limit their applications in the industrial sector. An alternative to these limiting factors is enzyme immobilization, which enables reuse and increases biocatalyst stability. Cellulose can be employed in enzyme immobilization, and is an outstanding alternative due to availability and cost. Additionally, this material might undergo several chemical treatments, thus obtaining cellulose nanocrystals and nanofibers. The use of nanomaterials at an industrial scale requires more refined unit operations to separate them, a setback that can be solved by combining these materials to magnetic nanoparticles. This review shows important aspects for the synthesis and application of nanocellulose and magnetic nanoparticles. It also reports new trends and strategies to associate these materials. Magnetic cellulose is a versatile support for enzyme immobilization, so much so that different immobilization methods might be conducted using this material.
