Abstract

The present disclosure relates, in some embodiments, to pre-concentrator compositions, devices, systems, and/or methods for concentrating small quantities of chemical or biological compounds, e.g., CBRNE compounds. A pre-concentrator of the disclosure may be operable to releasably bind and concentrate CBRNE compounds. In some embodiments, a pre-concentrator may comprise a 3-D structure of electrospun nanofibers, that comprise at least one polymer, one conducting agent and at least one chemical-specific functional group and/or biological-specific moiety configured to selectively bind to a CBRNE compound. Bound compounds may be released and detected. Pre-concentrator devices and systems operable to bind, concentrate, and/or detect one or more CBRNE compounds are described. Devices and systems of the disclosure may be configured to concentrate and detect multiple compounds. Methods for synthesizing pre-concentrators as well as methods for concentrating, detecting and identifying compounds of interest are also set forth.
