Optical sensor membranes having improved barrier properties |
摘要 |
The present invention discloses novel polymer compositions comprising cellulose acrylamide, acrylamide and/or a fluorescent indicator species, and membranes made with these compositions. Optical pH sensors for monitoring the pH in a fluid sample, and methods for making such pH sensors are also disclosed. The pH sensors have reduced sensitivity to sample components that can interfere with pH measurements.
