Review of Recent Development on Preparation, Properties, and Applications of Cellulose-Based Functional Materials

Functionalization strategies with expected high loading density used to immobilize the fluorescent sensing protein CPC to TEMPO-oxidized nanofibrillated cellulose (TONFC). Direct coupling was achieved by incubating CPC with previously EDC/s-NHS-activated TONFC suspensions. Lateral cross coupling combined physical immobilization of CPC to TONFC with subsequent glutaraldehyde-mediated coupling of CPC molecules. Reprinted from [12].
