Abstract
Sensing in reverse: Reversible detection of as few as 109 molecules (1700 am) of dimethyl methylphosphonate, a nerve agent simulant, is demonstrated at the end of a micro GCcolumn (see picture). Such arrays form the basis of rapidly transducing molecular sensors with micrometer-sized footprints. The separation capability of the column eliminates the need for selectivity on the sensor, as long as analyte binding is reversible and rapid. (Figure Presented) © 2008 Wiley-VCH Verlag GmbH & Co.
