Abstract

A piezoelectric 10 MHz multichannel quartz crystal microbalance (MQCM), coated with six molecularly imprinted polystyrene artificial recognition membranes have been developed for selective quantification of terpenes emanated from fresh and dried Lamiaceae family species, i.e., rosemary (Rosmarinus Officinalis L.), basil (Ocimum Basilicum) and sage (Salvia Officinalis). Optimal e-nose parameters, such as layer heights (1–6 KHz), sensitivity
Keywords: quartz crystal microbalance; chemical sensor; molecular imprinting; herbs; terpenes quartz crystal microbalance; chemical sensor; molecular imprinting; herbs; terpenes
