Abstract :
Processes of biological and biochemical
mechanisms are significant players in a host of scientific
fields, and it is important to promptly monitor the
parameters involved in these processes. The conversion
of biological data into an electrical signal has proven
difficult in the times past, necessitating the need for
technological devices for the analysis of these data and
signals with real-time ease and precision. The analytical
device that aids the conversion of a response from
biological and/or biochemical interactions into an
electrical signal is referred to as a biosensor; described
often as a system made up of three-element including a
bio-receptor, a transducing element and a signalprocessing unit. Biosensors work through the
incorporation of a biological or bio-recognition element
to determine a specific analyte embeded with a
transducer that is able to convert the biological signal
into an electrical signal, for onward interpretation by the
end-user. They are classified either by the type of
biological signalling mechanism, or the type of signal
transduction mechanism employed. Biosensors have the
ability to measure molecules that are non-polar and do
not respond to most measurement devices. They are easy
and efficient to use, ultra-sensitive, with high specificity,
and can be controlled rapidly and continuously.
However, biosensors are impeded by heat sterilization,
causing the denaturation of the biological material, and
they can also be extremely expensive. In a variety of
scientific areas of research and development such as
monitoring of environmental impacts and pollution,
medical diagnosis and clinical medicine, industrial
processes, agriculture and food safety, defence and
security, biosensors have found huge application
