The first part reviews the methods for preparing cellulose thin films. This review focuses on the challenges and opportunities provided by engineering cellulose thin films for controlling biomolecules interactions. Here, the cellulose thin film serves as a substrate for biomolecules interactions and acts as a support for bio-diagnostics. The three liable-OH groups on the monomeric unit of the cellulose chain provide schemes to chemically modify the cellulose interface and engineer its properties. These attractive film properties create many possibilities for both fundamental studies and applications, especially in the biomedical field. In particular, cellulose films of nanoscale thickness (1–100 nm) are transparent, smooth (roughness <1 nm), and provide a large surface area interface for biomolecules immobilization and interactions.
