Abstract: Inorganic nanosheets, which are obtained by exfoliation of layered materials such as graphites, are unordinary colloidal particles as characterized by the ultimately anisotropic shape with uniform 1 nm thickness and lateral size of microns. Due to spontaneous orientation of the anisotropic particles, the colloids of nanosheets form liquid crystal phases, depending on the size and concentration. Combinations of liquid crystalline nanosheets with synthetic polymers, biopolymers, or living bacteria opens lead to variation of composite materials with regulated structures applicable. in many ways such as soft-actuators and sensors. The fundamentals of liquid crystalline nanosheets and our recent application researches will presented in this lecture
