If you coat the inside of a microfluidic channel with poly-L-lysine, you can use it to influence signals in chemical reaction networks, reports ChemSystemsChem.

Equilibrium is essential: (bio)chemistry is full of it. In nature, it is still a little more elegant than what you can produce in the lab, but that does not stop chemists from creating equilibrium systems themselves. Hazal Koyuncu, Albert Wong and colleagues at the University of Twente have created such a system, which will ultimately allow information to be processed at the molecular level using chemical reaction networks (CRNs). This has earned them a place on the cover of ChemSystemsChem.
