DNA-nanoparticle motors are exactly as they sound: tiny artificial motors that use the structures of DNA and RNA to propel motion by enzymatic RNA degradation. Essentially, chemical energy is ...

Researchers have optimized DNA-nanoparticle motors to achieve speeds of 30 nm/s, matching natural motor proteins. By enhancing RNA enzyme activity and hybridization rates, the team reduced pauses and ...

The motion of motor proteins on biopolymers is important for diverse biological processes. Actin, microtubules, and nucleic acids can serve as one-dimensional tracks on which motor proteins move.
