In Color on the Front Cover (Top) A binding site in a molecularly imprinted polymer selectively binds an analyte; the polymer is used for chemical sensing. See “Molecularly Imprinted Polymers and Their Use in Biomimetic Sensors” by Karsten Haupt and Klaus Mosbach, p 2495. (Bottom) Sequence of cellular events that result in the expression of a reporter gene and subsequent emission of a measurable signal in the presence of a target analyte. See “Genetically-Engineered Whole Cell Sensing Systems: Coupling Biological Recognition with Reporter Genes” by Sylvia Daunert, Gary Barrett, Jessika S. Feliciano, Ranjit S. Shetty, Suresh Shrestha, and Wendy Smith-Spencer, p 2705. In Color on the Back Cover (Top, left) Hypothetical chelating binding mode for Vaska’s complex on (0001) CdSe, representing a sensor transducer. (Reprinted with permission from Brainard, R.

(Left, second from top) Poly(phenylene ethynylene), which exhibits self-amplification due to exciton migration, is an ultrasensitive TNT sensory polymer. The rigid three-dimensional pentiptycene scaffolds prevent interpolymer aggregation and produce porous electron-donating and TNT binding polymer films. See “Conjugated Polymer-Based Chemical Sensors” by D. Tyler McQuade, Anthony E. Pullen, and Timothy M. Swager, p 2537. (Left, second from bottom) Vapor response pattern from an array of polymer-coated acoustic wave sensors. See “Acoustic Wave Microsensor Arrays for Vapor Sensing” by Jay W. Grate, p 2627. (Center, second from bottom) Two-point calibration system on a compact disc (CD) based fluidic platform. See “From Batch to Continuous Manufacturing of Microbiomedical Devices” by Marc Madou and John Florkey, p 2679. (Bottom) Fabrication of a multisensor cross-reactive optical array on the etched face of an optical imaging fiber. The complementary-sized microsensors assemble into the microwells in an addressable fashion. See “Cross-Reactive Chemical Sensor Arrays” by Keith J. Albert, Nathan S. Lewis, Caroline L. Schauer, Gregory A. Sotzing, Shannon E. Stitzel, Thomas P. Vaid, and David R. Walt, p 2595.
