Self-assembly of various guest substrates in natural cellulose substances to functional nanostructured materials

► Mercury ion sensor was fabricated by dye nanocoating of cellulose nanofibers. ► Titania-coated carbon nanofibrous material was fabricated. ► Cellulose based luminescent or superparamagnetic materials were synthesized. ► Conductive sheets were made by coating cellulose fibers with carbon nanotubes.
