Letting molecular robots swarm like birds

The world's smallest 'swarm robot' measures 25 nanometers in diameter and 5 micrometers in length, and exhibits swarming behavior resembling motile organisms such as fish, ants and birds.

These include the formation of complex structures, distinct divisions of labor, robustness and flexibility, all of which emerge through local interactions among the individuals without the presence of a leader.'

In the present study, Kakugo and his collaborators have built a molecular system that is composed of the three essential components of a robot: sensors, information processors and actuators.

Microtubules are filamentous proteins that serve as the railways in the cellular transportation system, while kinesins are motor proteins that run on the railways by consuming chemical energy obtained from hydrolysis of adenosine triphosphate (ATP).

The chemically synthesized DNA molecules with certain programs in their sequences are conjugated to the microtubules labeled with green or red fluorescence dye.

The system acts as a basic computer by executing simple mathematical operations, such as AND or OR operations, leading to various structures and complex motions.
