The intrinsic structure and characteristics of polysaccharides make them suitable for forming
stimuli-responsive nanosystems. Recently, a variety of polysaccharides have been applied to develop
the sensitive nanomaterials for therapy, diagnosis and their combination. The mini-review intends
to present the stimuli-responsive polysaccharides-based nanotheranostics through elucidating the
typical examples of designing, preparing and applying the intelligent polysaccharides-based nanosystems
published during the last five years. The relationship between the structure of polysaccharides
and the function of the obtained nanosystems is discussed as well.
