天然纤维素片可以作为蛋白质固定化的底物。单独的纤维素纳米纤维首先被覆盖超薄的二氧化钛层，以实现对生物素的化学吸附，然后锚定链霉亲和素。这种薄片对生物分子具有很高的结合能力(见荧光显微镜照片)，而不会降低其机械和吸水性能(如图所示)。
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.(Figure Presented).
