Development of QCM sensor based on β-CD with thiol functional group for sensing 2-nonenal

uman body odor consists of various kinds of odor components. Among them, 2-nonenal which is representative material
of old man odor occurs by oxidation of skin secretion. In order to measure 2-nonenal, Gas Chromatography-Mass
Spectrometer (GC-MS) can be used as odor analyzer, but this analysis is difficult because of its very expensive cost, long
measurement time, and sampling odor directly. On the other hand, Quartz Crystal Microbalance (QCM), sensor can easily be
used for sensing human body odor because of cheap cost, short response time and without sampling. However, in order to use
QCM sensor, the host compound, which is the selective compound of human body odor, is need for preparing QCM sensor.
So, we have selected the β-cyclodextrin (βCD) as host compound in order to sensing 2-nonenal as guest compound. To deposit
βCD on QCM sensor, we introduced thiol functional group in the βCD, and then the thiol functional group introduced βCD
(βCD-SH) was modified on QCM electrode in DMSO/H2O (3:1, v/v) mixed solution of βCD-SH. Successful synthesis of βCD-
SH was characterized via H-NMR, FT-IR and MS. Preparation of the QCM sensor based on βCD was characterized via X-ray
Photoelectron Spectroscopy (XPS), Energy Dispersive Spectroscopy (EDS) and contact angle. Also, reliability of measured data
was compared with GC-MS data. Finally, we measured the adsorption and desorption properties according to concentration
of 2-nonenal by QCM analyzer.
