Recent advances in electrochemical biosensors based on graphene two-dimensional nanomaterials

“…Among the numerous nucleic acid assay methods, electrochemical DNA sensors hold promising potential for DNA analysis and sequencing , Liu et al, 2012c. Graphene and graphene-based nanocomposites exhibit several advantages and exceed other electrode materials in the catalytic oxidation of the four DNA bases by their exposed edgelike planes (Vashist andLuong, 2015, Wang et al, 2013b). Significant contributions have been made to the synthesis of various graphene-like nanomaterials, which are expected to be employed in the construction of novel sensing platforms for the sensitive and selective detection of DNA bases, nucleotides, single-stranded DNA (ssDNA), and double-stranded DNA (dsDNA) (Gao et al, 2014a, Akhavan et al, 2012.…”

“…fuel cells, batteries and supercapacitors) and biological applications. Its high specific surface area and the ease of functionalizing its surface can accommodate highly active probes and targets of interest, which is favorable for developing a novel bio-interface for biosensing (Vashist and Luong, 2015, Ping et al, 2015, Fang and Wang, 2013, Liu et al, 2012c, Pumera, 2010. Moreover, the recently successful synthesis of graphene nanosheets via various protocols and the integration of graphene with different nanomaterials, such as metals, metal oxides, and quantum dots, could provide abundant opportunities for developing novel biosensors with enhanced performance (Mao et al, 2013).…”
