Surface pretreatment boosts the performance of supramolecular affinity materials on quartz crystal microbalances for sensor applications.
A Teflon-like coating is the key for the boost in sensitivity of quartz microbalances for the tracing of airborne analytes. Since the undesired signals for the interfering compounds are suppressed and the ones for the targeted compounds (e.g., peroxide explosives) are enhanced, the PCA output is improved.
