Abstract
A novel optical pH sensor for the physiological range has been developed by these authors. The fluorescence emitted tin a pH-independent manner) by dy e-doped polymer nanobeads is modulated by a thin conductive polymer coating (see Figure), whose visible-light absorption strongly varies with pH at va lues around seven.
