Title Mass-sensitive detection of solvent vapors. Mechanistic studies on host-guest sensor principles by FT-IR spectroscopy and BET adsorption analysis Type Journal Article
Year 1996 Publication Analytical Chemistry Abbreviated Journal Anal. Chem.
Volume 68 Issue 6 Pages 1058-1061
Keywords supramolecular recognition, quartz crystal microbalance, QCM, surface acoustic wave, SAW, mass-sensitive sensor, detector, calixarenes, MM3 force field, Brunauer, Emmett and Teller theory, BET
Abstract Chemical sensors, based on highly mass sensitive QMB or SAW devices, coated with thin layers of calixarenes, enable the detection of organic solvent vapours, especially halogenated or aromatic hydrocarbons, down to a few ppm. Force field calculations allow the tailoring of these sensor materials seeing that the predicted interaction energies between the host molecules and a large variety of analytes are linearly correlated to the measured sensor effects. These correlations and also BET adsorption analysis prove the analyte recognition properties of these calixarene coatings to be mainly based on host/guest inclusion principles.

Title Chemosensors in environmental monitoring: challenges in ruggedness and selectivity Type Journal Article
Year 2009 Publication Analytical and Bioanalytical Chemistry Abbreviated Journal Anal Bioanal Chem
Volume 393 Issue 2 Pages 467-472
Keywords environmental monitoring, in situ sensing, artificial recognition materials, real-life application, molecular imprinting, QCM
Abstract Environmental analysis is a potential key application for chemical sensors owing to their inherent ability to detect analytes on-line and in real time in distributed systems. Operating a chemosensor in a natural environment poses substantial challenges in terms of ruggedness, long-term stability and calibration. This article highlights current trends of achieving both the necessary selectivity and ruggedness: one way is deploying sensor arrays consisting of robust broadband sensors and extracting information via chemometrics. If using only a single sensor is desired, molecularly imprinted polymers offer a straightforward way for designing artificial recognition materials. Molecularly imprinted polymers can be utilized in real-life environments, such as water and air, aiming at detecting analytes ranging from small molecules to entire cells.
