Abstract
In an embodiment, a benzene sensor comprises a substrate having an iodine complex disposed thereon, a radiation source configured to project UV radiation onto the complex, and a UV detector configured to detect a UV reflection off of the substrate having the iodine complex. The iodine complex can include a cyclodextrine-iodine complex such as an alpha-cyclodextrine-iodine complex, a β-cyclodextrine iodine complex, or any combination thereof.

1-15. (canceled)
A benzene sensor comprising:
- a substrate having an iodine complex disposed thereon;
- a radiation source configured to project UV radiation onto the complex;
- and
- a UV detector configured to detect a UV reflection off of the substrate having the iodine complex.
A method for sensing benzene comprising:
- exposing benzene to an iodine complex;
- forming an iodine-benzene complex;
- irradiating the iodine-benzene complex with UV radiation;
- detecting a UV absorption in the intensity of radiation reflected from the iodine-benzene complex;
- and
- determining that benzene is present based on the absorption of the UV radiation in the reflected radiation.
A method for sensing benzene comprising:
- exposing a substrate having an iodine complex disposed thereon to a gas comprising benzene;
- forming an iodine-benzene complex in response to the exposing;
- irradiating the iodine-benzene complex with UV radiation from a radiation source;
- reflecting at least a portion of the UV radiation from the iodine-benzene complex;
- detecting a UV absorption in at least the portion of the UV radiation reflected from the iodine-benzene complex;
- and
- determining that the benzene is present in the gas based on the detected UV absorption in the UV radiation reflected from the iodine-benzene complex.
