A system, apparatus, and method include a pump to deliver vapor including airborne contaminants including organic compounds including a target analyte; a collector to transfer the airborne contaminants by autonomous liquid extraction into a mobile organic liquid phase; a micro-fluidic chamber including immobilized biorecognition elements that bind to analytes delivered from the mobile organic liquid phase; a mechanism to introduce the mobile organic liquid phase to a buffer containing a plurality of substrates causing a series of biochemical reactions that create a change corresponding to a concentration of the target analyte; and a detector to perform real-time analysis that correlates to a concentration of the organic compounds to determine a presence of the target analyte.

A biosensor that utilizes carbon nanotubes functionalized with a protein sequence. One domain of the multifunctional peptide sequence noncovalently binds to the surface of single-walled carbon nanotubes (SWNTs), while a second domain of the sequence recognizes and binds to a target molecule. The sequence of the peptide may be tailored to allow it to recognize and bind to specific target molecules, such as chemicals, biological materials, and explosives. The binding of the target molecule to the peptide may alter a material property of the SWNTs.
