12.3.1 Optical Biosensor
The optical measurement principle is used in the optical biosensor devices. They also
use optical fiber as well as optoelectronic transducers for its process. The word opt
rode which represents the compression of two terms optical and electrode [9, 10].
The main purpose of this sensor is involving in transuding elements like antibodies
and enzymes. This biosensor allows us to secure non-electrical inaccessible sensing
equipment. One of the extra benefits of this sensor is it doesn’t require/need reference
sensors frequently like other sensors. The optical biosensors are broadly divided into
two categories such as direct and labeled optical detection biosensors.
12.3.2 Thermometric Biosensor
In our daily life, huge number of biological reactions takes place those are mainly
interconnected with heat, and this makes the base for the invention/formation of
thermometric biosensors. Usually, these kinds of sensors that deal with heat are
referred to as thermal (heat) biosensors. To measure/estimate/calculate the serum
cholesterol this thermometric-biosensor is used in a wide range [11]. It is also used
for the known glucose value, to find the amount of urea, and penicillin G can be done
with these biosensors.
There are many numerous applications of biosensors available according to the
need. The need for a biosensor in our daily activities is tremendous broadly used in
the biological area and commercial applications like identifying the target molecules,
recognition of biological elements, and the tendency of the disposable portable detection system in some situations [12, 13]. Diabetes patients to monitor the glucose
levels, targets related to medical health departments, general applications like detection of pesticides for farmers in agriculture and water contaminants (river, lake) and
some of the metal ion compounds, sensing remotely for the airborne virus in Bioware
activities, checking water quality in coastal waters by explaining clam ethnology in
groups bivalves around the world in online, pathogens detection, toxic substances
determination for bioremediation before and after and organophosphate detection,
folic acid, pantothenic acid routine analytical measurement as an alternate for microbiological assay, drug residues in food determination (antibiotics and promoting the
growth of the viruses, mainly the flesh of an animal and honey), biological activity
and the origin of new devices, and toxic detection metabolites like mycotoxins [14].
12.3.3 Progress of SARS-Corona Virus Disease
All human coronaviruses are basically from animal origins, termed as, natural hosts.
Particularly bats are one of the Human coronavirus 229E, SARS-Corona Virus,
