The molecular propellers designed in the group of Prof. Petr Král from the University of Illinois at Chicago have their blades formed by planar aromatic molecules and the shaft is a carbon nanotube.
[3] Molecular dynamics simulations show that these propellers can serve as efficient pumps in the bulk and at the surfaces of liquids.
[7] Nature realizes most biological activities with a large number of highly sophisticated molecular motors, such as myosin, kinesin, and ATP synthase.
[8] For example, rotary molecular motors attached to protein-based tails called flagella can propel bacteria.
[9] Future applications of these nanosystems range from novel analytical tools in physics and chemistry, drug delivery and gene therapy in biology and medicine, advanced nanofluidic lab-on-a-chip techniques, to tiny robots performing various activities at the nanoscale or microscale.
