Limonene
is a type of terpene hydrocarbons
commonly produced by plants and known to possess a strong
smell of oranges. Electronic nose (e-nose) is an artificial
olfaction device that is able to replicate the human olfactory
sense. By using Interdigitated Electrode (IDE) structure, an e-
nose sensor for detecting Limonene volatile by using
molecular imprinted polymer (MIP) was fabricated. The MIP
membrane contained the methacrylic acid, which formed
specific cavities originated by target molecule. The
ingredients for MIP were then polymerized on the surface of
IDE with PET as substrate which is low in cost. The sensing
property was examined in gas phase for evaluate the sensor
sensitivity and selectivity. The IDE MIP sensor is capable to
detect Limonene contained gas. The sensor characteristics
were strongly influenced by the composition ratio of cross-
linker, functional monomer and template molecule. The
remained molecule on MIP can be removed by immersing
thus the sensor can be used repeatedly. By determining
Limonene volatile released during pre-matured until matured
period, one could use this as a data point to determine certain
fruit maturity. Apart from monitoring fruit maturity, this
sensor can also be use for those who have respiratory allergy
towards Limonene where most reported cases of irritation
have involved long-term industrial exposure to the pure
compound,
e.g.
during degreasing or the preparation of
paints.
