Graphene
is considered as a promising electronic material in post silicon
electronics. Due to the unusual physical and electronic properties, as
well as excellent charge-carrier mobility, graphene quickly grabbed the
attention of physicists and engineers, bringing a hope that one day it
will compete with silicon to be the material of next generations for
certain applications in the electronics industries. It is
believed that the graphene based nanodevices can be easily extended to
large-scale integration (in contrast to carbon nanotube electronics)
and can rank among the most important achievements in nanoelectronics,
possibly outweighing other alternatives such as molecular and nanotube
electronics. However, the process has inherent disadvantages in terms
of yield and throughput. An effective approach in this regard was based
on chemical exfoliation of graphite to graphene oxide (GO). The
resultant material consists of graphene-derived sheets and is heavily
oxygenated with hydroxyl, carbonyl and carboxylic functional groups.
Thus, the hydrophilic GO sheets can remain as highly stable aqueous
dispersions. Due to the presence of oxygen-containing functional groups
provides potential advantages to GO for numerous applications in the
field of nanocomposites, Biosensors, and Drug Delivery.
In this regard, this communication discuss the production and atomic
resolution imaging of graphene, graphene oxide and graphene based
hybrid material for example decoration with metal NPs (Ag/or Au) and
polymer grafting. Graphene could potentially display not only the
unique properties of Au/ or Ag, but also additional novel properties
due to interaction between the Au/ or Ag NPs and the graphene. Many
exciting applications can be envisioned from these novel hybrid
nanostructures for potential applications such as biosensors,
controlled drug delivery, chemical sensors, nanoelectronics,
Photovoltaic cells, fuel cells, Catalysts.
