ABSTRACT:
For the purpose of reversible optical indication of the pH of a sample, a hydrophilic accommodating layer is disposed on a hydrophobic mechanically stable support element, which layer contains the indicator dye proper in an immobilized form. This provides a sensor membrane which can be fabricated in a simple manner and is cost-effective, which has a rapid response time and can also be fabricated as a mass product to be used only once.
