摘要：
Natural cellulose sheets can be used as substrates for protein immobilization. Individual cellulose nanofibers are first coated with ultrathin titania layers to enable the chemisorption of biotin, and then streptavidin is anchored. The sheets have a high binding capacity for biomolecules (see the fluorescence micrographs) without deterioration of their mechanical and water-absorbing properties.
