These "picosprings" have remarkably large and tuneable compliancy and can be controlled remotely through magnetic fields (even deep within the human body) allowing articulated motion in microrobots as well as micromanipulations well beyond the state of the art.
A study published in Light: Science & Applications demonstrates a significant advancement in an era where understanding and controlling light at the nanoscale is becoming increasingly important.
Recently, a group of scientists created a fluorescent nanosensor that requires no batteries using single-wall carbon nanotubes and an inactive version of the enzyme glucose oxidase (GOx).
