AB  - The dispersion of nanoparticles having different size-, shape-, and 
      composition-dependent properties is an exciting approach to design and synthesize 
      multifunctional materials and devices. This work shows a detailed investigation 
      of the preparation and properties of free-standing nanocomposite films based on 
      cellulose nanocrystals (CNC) loaded with three different types of metal 
      nanoparticles. CNC-based nanocomposites having zinc oxide (ZnO), titanium dioxide 
      (TiO(2)), and silver oxide (Ag(2)O) have been obtained through 
      evaporation-induced self-assembly (EISA) in acqueous solution. Morphological and 
      optical characteristics, chemical properties, wettability, and antimicrobial 
      assays of the produced films were conducted. Furthermore, disintegrability in 
      composting condition of CNC based nanocomposites was here investigated for the 
      first time. The morphological observations revealed the formation of a chiral 
      nematic structure with uniformly distributed nanoparticles. The bionanocomposite 
      films based on the metal nanoparticles had effective antimicrobial activity, 
      killing both Escherichia coli RB ( E. coli RB) and Staphylococcus aureus 8325-4 ( 
      S. aureus 8325-4). The simplicity method of film preparation, the large quantity 
      of cellulose in the world, and the free-standing nature of the nanocomposite 
      films offer highly advantageous characteristics that can for the new development 
      of multifunctional materials.
