electrodes have been prepared by impregnating metallic NPs or CNTs along
with biomolecules. Immobilization of biomolecules on QDs has been suc-
cessfully applied in several cases. Platforms like NW FETs and cantilevers
have attracted great interest.
Biosensors are animated with the application of the enlivening biomol-
ecules on suitable platforms. Without these molecules, they are senseless. As
the effect of these biomolecules weakens, biosensors lose their senses and
ultimately stop functioning. Therefore, biosensors need careful attention
to storage and handling. They should also be used with caution bearing in
