The current article presents experimental observations of erythrocytes aligning in nematic liquid crystal (NLC) medium as well as following study of the rearrangement of the NLC matrix induced by aligned bodies. The results of this study showed that a pronounced rearrangement of a pristine NLC mesophase could be induced not only by the insertion of fullerenes or fullerene-based charge-transfer complexes, but by adding non-electrically-neutral biological components such as human blood erythrocytes.
