Abstract

This study proposes a novel quartz crystal microbalance-based sensor using polyvinyl acetate nanofbers overlaid with maltodextrin to enhance sensitivity toward trimethylamine (TMA) gas. The sensor demonstrated a remarkable increase in sensitivity by 8.3 times, with a detection limit of 15.6 ppm. The enhanced sensitivity is due to reversible intermolecular Lewis acid–base interaction between active groups of maltodextrin and TMA gas molecules. Moreover, the sensor exhibited good selectivity, stability, and fast response and recovery times of 141 s and 116 s, respectively. The proposed sensor offers a promising alternative to conventional methods for accurately monitoring TMA gas levels in the air.
