Immobilization of TiO 2 nanoparticles onto paper modification through bioconjugation

TiO2 is commonly used as a brightening agent for paper, but may also be used on paper as a photocatalyst. The TiO2 aggregates that typically form in/on paper are inefficient both for brightening or photooxidation. We describe, for the first time, the preparation of homogeneously distributed, non-aggregated TiO2 particles on cellulose fibers using explicit bioconjugation with the fusion protein of CBM2a-Strep-tag II/streptavidin/biotinylated …
