Graphene: An overview of its characteristics and applications

Graphene exhibits excellent distinct characteristics due to their lightweight and honeycomb structure. Due to these unique properties, graphene attracted number of researchers from diversified fields. Its applications are found in opto-electronics, electronics and biomedical sectors. These nanomaterials show some toxicity effects for biomedical applications, which are explained by the researchers working in this field in a limited manner. Due to which the toxic effect of these materials is still not well explained. Therefore, it became essential to analyze the characteristics of graphene and its potential application. The main aim of this review is to compile all the information (up-to-date) on its characteristics and applications, like energy, electronics, sensors and filed emission. Some challenges are discussed in conclusion section to provide the direction to the researchers for future research.
