摘要：

β -1,3-Glucans act as unique natural nanotubes, the featuresof which are greatly different from other natural or synthetic helical polymers. The origin mostly stemsfrom their strong helix-forming nature and reversible interconversion between single-strand random coiland triple-strand helix. During this interconversion process, they can accept functional polymers, molecularassemblies and nanoparticles in an induced-fit manner to create water-soluble one-dimensional nanocomposites,where individual conjugated polymers or molecular assemblies can be incorporated into the one-dimensionalhollow constructed by the helical superstructure of β -1,3-glucans.The advantageous point of the β -1,3-glucan hosting system is thatthe selective modification of β -1,3-glucans leads to the creationof various functional one-dimensional nanocomposites in asupramolecular manner, being applicable towardfundamental nanomaterials such as sensors or circuits. Furthermore, the composites with functional surfacescan act as one-dimensional building blocks toward further hierarchical self-assemblies, leading to the creationof two- or three-dimensional nanoarchitectures.
