1-26. (canceled)
A device comprising:
- a substrate having a surface, said surface having thereon at least one detection region comprising a liquid crystal composition that interacts with an analyte in a gaseous phase;
- and
- a housing having an opening therein, said substrate configured in said housing so that said detection region is exposed to the outside of said housing through said opening.
A device comprising:
- a substrate having a surface, said surface having thereon at least one detection region comprising a feature selected from the group consisting of a grid, a channel, a plurality of channels, a plurality of pillars, or an array of assay areas or combination thereof;
- a liquid crystal composition that interacts with an analyte phase;
- and
- a housing having an opening therein, said substrate configured in said housing so that said detection region is exposed to the outside of said housing through said opening.
