Abstract
There has been a considerable interest in 3 b C d 8
developing new as.stiys fo r fo o d analysis to meet the
tieiminds o f the different regulatory health agencies.
Biosensors offer a new alternative due to their inherent
specificity, simplicity anti quick response. A biosensor is
an analytical device fo r the detection o f an analyse that
coni bines a biological component with a
physicochemical detector component. Depending on the
nature o f the transducers and the transduced parameter,
*there are different types such as Electrochemical,
Piezoelectric, and Thernionietric and Optical biosensors
in the analytical field. A s a result o f the development o f
the microprocessor appiied leciinology and rapid growth
o f biotechnology, production and application o f
biosensors expan tied tiramaticaily. Although human
sense organs are sensitive, instruments provide better
quantitative results than them. However conventional
instrumental methods are incompatible in cases where
quick results are needed, in addition to this, biosensors
have various advantages as compared to conventional
analytical methods. They are relatively cheap, easy to
handle, portable and the user does not require special
skills.
