10.3762/bjnano.5.42 Abstract The polysaccharide xanthan has been extensively studied owing to its potential application in tissue engineering. In this paper, xanthanscaffold structures were investigated by atomic force microscope (AFM) in liquid, and the mechanical properties of the complex xanthan
structures were investigated by using AFM-based force spectroscopy (FS). In this work, three types of structures in the xanthanscaffold were identified based on three types of FS stretching events. The fact that the complex force responses are the combinations of different types of stretching events
suggests complicated intermolecular interactions among xanthan fibrils. The results provide crucial information to understand the structures and mechanical properties of the xanthanscaffold.
Keywords: atomic force microscopy (AFM); force spectroscopy (FS); mechanical properties; xanthanscaffold
