Journal ArticleDOI
Cross-reactive chemical sensor arrays.
Keith J. Albert,Nathan S. Lewis,Caroline L. Schauer,Gregory A. Sotzing,Shannon E. Stitzel,Thomas P. Vaid,David R. Walt +6 more
TL;DR: Conventional approaches to chemical sensors have traditionally made use of a “lock-and-key” design, wherein a specific receptor is synthesized in order to strongly and highly selectively bind the analyte of interest.
Journal ArticleDOI
High-Speed Fluorescence Detection of Explosives-like Vapors
Keith J. Albert,David R. Walt +1 more
TL;DR: It is shown that single-element arrays permit the detection of low-level nitroaromatic compound vapors because of sensor-to-sensor reproducibility and signal averaging.
Journal ArticleDOI
Cross-Reactive Chemical Sensor Arrays
Keith J. Albert,Nathan S. Lewis,Caroline L. Schauer,Gregory A. Sotzing,Shannon E. Stitzel,Thomas P. Vaid,David R. Walt +6 more
TL;DR: In this article, a lock-and-key approach is used to detect compounds in the presence of controlled backgrounds and interferences, which requires the synthesis of a separate, highly selective sensor for each analyte to be detected.
Journal ArticleDOI
Optical multibead arrays for simple and complex odor discrimination.
TL;DR: The utility of the fiber optic bead-based sensor array technology for discriminating between different odor types at various dilution levels is demonstrated for the first time.
Journal ArticleDOI
Field-deployable sniffer for 2,4-dinitrotoluene detection.
Keith J. Albert,Michael L. Myrick,Steve B. Brown,Dale L. James,Fred P. Milanovich,David R. Walt +5 more
TL;DR: A field-deployable instrument has been developed to detect low-level 2,4-dinitrotoluene (2, 4-DNT) vapors based on previously developed artificial nose technology and employs an array of sensory materials attached to the distal tips of an optical fiber bundle.
