Notes:
A newly emerging trend of Chitosan-Based sensing platform for the Organophosphate
pesticide detection using Acetylcholinesterase

Organophosphate pesticides have been
extensively used to protect the agricultural
produce from being damaged by the pests while
growing and the subsequent degradation in its
quality. However, in the process of doing so, the
pesticides and their degradation products, enter
the soil and water and start accumulating in the
food products. Consequently, the remnants of the
pesticide or its degradation products concentrate
in the food products, they can be potentially
damaging to the central nervous system of human
beings when consumed. There is the plausibility
of deteriorating health in the individual when
the key enzyme, Acetylcholinesterase, which
is responsible for the orderly functioning of the
nervous system, is inhibited by the pesticides.
This review gives an insight into the recent
approaches towards the rapid sensing of the
deleterious pesticides. Numerous sensing
platforms, comprising of chitosan as the key
element of the immobilization matrix for the
subsequent binding of acetylcholinesterase
have been highlighted in this study. Chitosan
plays the decisive role in helping maintain the
activity of the acetylcholinesterase immobilized
by various techniques. The acetylcholinesterase
enzyme-inhibition based biosensors pave the
way for a speedy and feasible detection of the
organophosphate pesticides present in the food
articles by bypassing the copious pre-treatments.
They also carry the possibility to be used for
the real-life sample analysis. Thus, various
transducers have been used in combination
with the biopolymer chitosan, to produce highly
sensitive biosensors for the detection of even
trace amounts of these pesticides efficiently.
Speaker Biography
Hitika Hemant Patel currently working as a Food Chemist at Analytical
and Environmental Services, Vadodara. Here, She analyzing and testing
the various food products and water for their purity and nutritional value.
She also serve as a Microbiologist for the analysis of different food and
water samples. Her plan in the future is to achieve a PhD. She interested
in going for a research in the field of food technology for improving
the nutritional value of food products and in the development of new
commodities of food.
