Nanoputians are a series of organic molecules whose structural formulae appear human. James Tour et al. (Rice University) designed and synthesized these compounds in 2003 as a part of a sequence of chemical education for young students. The compounds consist of two benzene rings connected via a few carbon atoms as the body, four acetylene units each carring an alkyl group at their ends which represents the hands and legs, and a 1,3-dioxolane ring as the head.
