Abstract
Enzymes have catalytic properties and can be used for different purposes as
biocatalysts in some industrial processes. However, their applications are limited due to
some drawbacks, such as lack of long-term stability and recovery under conditions of
any particular process. Enzymes can improve their catalytic activity, stability,
reusability, and half life, if these are immobilized on some support. Graphene and
graphene based nanomaterials are good supports for enzymes as they are also non-toxic
materials in nature. Such materials can also find applications in the fields of medical
diagnostics, biofuel cells, biosensors, etc. These particular aspects have been discussed
in this chapter.
Keywords: Biocatalyst, Biofuel Cell, Biosensors, Graphene, Graphene Oxide, Immobilization, Reduced Graphene Oxide.
