Abstract

An understanding of analyte–coating interactions is needed in order to be able to predict the sensitivity and selectivity of coating materials considered for use in mass-sensitive devices such as the quartz microbalance. Models are reviewed for the sensor response based on solubility parameters and calculated energies for functionalized coatings and supramolecular cavities (e.g., the substituted tetraazaparacyclophane shown in the Figure).
