sensor stability is another factor. Hence for the on-site applications fewer pretreat-
ment sample preparation or direct analysis methods should be identifi ed. Utilizing the
advances in microfabrication technologies the development of miniaturized sensors or
disposable kits is highly benefi cial for household purposes and real-time analysis in
various sectors such as industry, medicine, etc. Although efforts have been made in the
development of multi-pesticide biosensors, in the future more emphasis is required to
design a highly selective multi-pesticide fl ow injection biosensor for the fast and auto-
matic analysis of real samples.
