ABSTRACT:
A protected, lipid membrane-based device useful as a chemoreceptive transducer is provided. The device includes a porous, membrane-protective layer attached to an underlying, lipid membrane. Also provided is a process for using the protected device to determine the concentration of a specified chemical species.
There is additionally provided a lipid membrane-based gas sensor. The sensor includes a gas-permeable, hydrated upper layer attached to an underlying lipid membrane. Furthermore, the invention includes a process for using the gas sensor to determine the concentration of an inorganic ion formed from an inorganic ion-forming gas.
