Biosensors are employed in applications such as disease monitoring, drug discovery, and detection of pollutants, disease-causing micro-organisms, and markers that are indicators of disease in bodily fluids (blood, urine, saliva, sweat).
2. What Is A Biosensor ?
A biosensor is an analytical device, used for the
detection of a chemical substance that combine a
biological component with a physiological detector.
The sensitive biological e.g tissue, microorganisms,
organelles, cell receptors, enzymes, antibodies,
nucleic acids etc. It is comprised of a specific
biological element and a transducer.
4. Resonant Biosensors
In a resonant biosensor, a transducer like an acoustic wave can
be connected through a bio-element. Once the analyte molecule is
connected toward the membrane, then the mass of the membrane
alters.
Magnetic Biosensor
These types of sensors are used to gauge changes within
magnetically persuaded effects or magnetic properties.These
kinds of sensors use crystals or particles of superparamagnetic
otherwise paramagnetic to detect biological communications
through measuring changes within magnetic properties like
changes within coil inductance, resistance.
6. OPTICAL BIOSENSORS
The optical biosensors is a device that uses an optical measurement principle.
They use fiber optics as well as optoelectronic transducers. The term optrode
represents a compression of the two terms optical and electrode.
7. THERMAL BIOSENSORS
This type of biosensor work on
the fundamental properties of
biological reactions, namely
absorption or production of
heat, which in turn changes
the temperature of the medium
in which the reaction takes
place.
They are constructed by
combining immobilized enzyme
molecules with temperature
sensors.
8. WEARABLE BIOSENSORS
The wearable biosensor is a digital device, used to wear on the human body
in different wearable systems like smartwatches, smart shirts, tattoos
which allows the levels of blood glucose, BP, the rate of heartbeat etc.
