Metal–organic frameworks (MOFs) have great potential in quartz crystal microbalance (QCM) platforms for volatile organic compound (VOCs) detection and recognition due to their unique properties. However, the MOFs' hydrophilicity degrades performance high-humidity environments, limiting reliable VOC sensing complex environments. Herein, we propose a novel virtual sensor array (VSA) using single QCM with an adsorption layer composed of MIL-101(Cr) MOF polydimethylsiloxane (PDMS), realizing...
