Color-changing nanopigment sensor tracks pH one to ten with stable, repeatable readings
Chemists in South Korea have created a stable color-changing sensor that displays an easily quantifiable response to the pH of its surroundings. Published in Microsystems & Nanoengineering, Dong-Hwan Kim and colleagues at Sungkyunkwan University say their approach could pave the way for more reliable, affordable pH measurements across a broad range of real-world scenarios.
