Rolling DNA-based motors increase nano-walker speeds 1000-fold

Coating micrometer-sized glass spheres with hundreds of DNA strands complementary to an RNA covering a glass slide enables the sphere to move, with the help of an enzyme that digests RNA bound to complementary DNA, a thousand times faster than conventional DNA-walkers.

Overview of molecular machines documents recent progress

A review of molecular parts that act as switches, motors, and ratchets illuminates similarities between artificial and biological molecular machines and argues that useful applications are coming.

Proof of principle for nanoscale assembly line

Swiss researchers have used biomolecular shuttles to capture molecular building blocks from solution and transport them across fluid flow boundaries to be further manipulated in a subsequent chamber.

DNA nanorobot walks without intervention along rigid track

Scientists have succeeded in coordinating the movements of the biped’s legs so that it can walk in one direction along a DNA track without the need of intervention at each step.

Meet the Nubot: DNA nanotechnology robots

Aharia Nair brings to our attention the new term Nubot, for Nucleic Acid Robots. Wikipedia explains: Nubot is an abbreviation for “Nucleic Acid Robots.” Nubots are synthetic robotics devices at the nanoscale. Representative nubots include the several DNA walkers reported by Ned Seeman’s group at NYU, Niles Pierce’s group at Caltech, John Reif’s group at… Continue reading Meet the Nubot: DNA nanotechnology robots
