Abstract
A method of detecting at least one noble gas through a semi-permeable membrane, allowing the permeating noble gas to contact an enzyme, the activity of which is changed by the noble gas, and detecting the change in enzyme activity.
Claims22
A method of detecting at least one noble gas with an enzyme-based sensor having at least one enzyme therein and having a membrane therefor which is at least semi-permeable to said at least one noble gas, which comprises:
- a) permeating said at least one noble gas through said membrane;
- b) contacting at least one enzyme in said sensor with an amount of said at least one noble gas sufficient to change an activity of said at least one enzyme;
- and
- c) detecting the change in the activity of said at least one enzyme;
- and
- wherein said at least one noble gas is selected from the group consisting of xenon, krypton, argon and neon.
