Abstract
Biosensors utilizing 4-acetoxyphenol are described. The biosensors typically include 4-acetoxyphenol in a substrate and utilize one or more enzymes to detect the presence of pollutant agents. Also described are related methods using the biosensors to detect the presence of pollutant agents in water such as As(III).
Claims17
A biosensor for analyzing a sample for pollutant agents in water, the biosensor comprising:
- a substrate;
- an electrode;
- and
- at least one enzyme immobilized on the electrode;
- wherein the substrate includes 4-acetoxyphenol.
2 more elements
A biosensor for analyzing a sample, the biosensor comprising:
- a substrate including 4-acetoxyphenol, the substrate defining a first face and a second face;
- a working electrode disposed on the first face of the substrate;
- a region including at least one enzyme disposed on the working electrode.
A method for detecting presence of a pollutant agent, the method comprising:
- providing a biosensor including a substrate having 4-acetoxyphenol, a working electrode disposed on the substrate, and a region including at least one enzyme disposed on the working electrode;
- exposing the biosensor to an aqueous sample;
- monitoring electrical activity at the working electrode.
