By carefully incorporating strands of custom DNA into different layers of flexible films, researchers can force those films to bend, curl and even flip over by introducing the right DNA cue. They could also reverse these changes by way of different DNA cues.
A team of mechanical engineers has successfully used acoustic waves to move fluids through small channels at the nanoscale. The breakthrough is a first step toward the manufacturing of small, portable devices that could be used for drug discovery and microrobotics applications.
A skin-like biomedical technology that uses a mesh of conducting nanowires and a thin layer of elastic polymer might bring new electronic bandages that monitor biosignals for medical applications and provide therapeutic stimulation through the skin.
