Description
Summary:The quartz crystal microbalance (QCM) technique has been applied to the direct mass measurement of a self-assembled monolayer of octadecyl mercaptan (OM) on a gold surface deposited onto a quartz crystal. Repeated rinsing of the modified electrodes with used solvent was conducted to get self-assembled monolayers of OM. From the resonance frequency change, 2.5 mu molecular occupied area of OM on Au was obtained. The advantage of the combination of QCM and electrochemical methods was emphasised for the characterisation of self-assembled monolayers.
