Prokaryotic flagellum is considered as the only known example of a biological “wheel,” system capable converting action rotatory actuator into continuous propulsive force. For this reason, flagella are an interesting case study in soft robotics and they represent appealing source inspiration for design underwater robots. A great number flagellum-inspired devices exists, but these ...

Abstract Biological muscles mainly consist of motor proteins that play essential roles and have a hierarchical structure covered with collagen can transmit the tension to bones via tendons. The artificial reconstruction is highly expected from viewpoint engineering biology. Although been developed synthetic biological molecular motors, there considerable gap between components muscles, resultin...

We have controllably positioned, with nanometre precision, single CdSe quantum dots referenced to a registration template such that the location of a given nanoparticle on a macroscopic (≈1 cm(2)) sample surface can be repeatedly revisited. The atomically flat sapphire substrate we use is particularly suited to optical measurements of the isolated quantum dots, enabling combined manipulation-sp...
