Single-chain nanoparticles morphology

Clear relationship - Low Mw chitosan 2D chains between - Medium molecular weight chitosan single nanoparticles morphology and - High molecular weight chitosan nanoplates molecular weight... 

Nanoparticles exist in spherical, mbe and whisker, and plate-like shapes and at least one of the three dimensions is required to be on a nanometric scale. Nanostructures of layered clays are further categorized as intercalated, in which the polymer chains have penetrated between the clay layers in a well-ordered multilayer morphology, and exfoliated, in which the clay layers have dispersed along the matrix and have no organized slnictme [7]. Carbon nanombes also exhibit two nanostructmes single-walled nanotube and mnltiwalled nanotube, which is composed of several tubes within each other.
