Single-molecule valve: a breakthrough in nanoscale control

Osaka, Japan (SPX) May 03, 2023 Scientists dream of using tiny molecules as building blocks to construct things, similar to how we build things with mechanical parts. However, molecules are incredibly small - around one hundred millionth the size of a softball - and they move randomly in liquids, making it very difficult to manipulate them in a single form. To overcome this challenge, "nanofluidic devices" that can transport m
