Synthesis of graphene supported graphene-like C3N4 metal-free layered nanosheets for enhanced electrochemical performance and their biosensing for biomolecules

Hybrid 2D-nanomaterials-based electrochemical immunosensing strategies for clinical biomarkers determination

“…Although much less explored than graphene-based, GLNs nanohybrids have demonstrated great potential also as electrode materials in the development of promising non-enzymatic sensors (Yang et al, 2014b;Sun et al, 2014;Xia et al, 2014;Gu et al, 2015) and enzymatic biosensors (Song et al, 2014b). However, only one example of an immunosensor for a clinical biomarker has been found in the literature.…”

Enhanced photochemical oxidation ability of carbon nitride by π–π stacking interactions with graphene

“…Particularly, it can be used as an electron mediator for shuttling electrons, leading to the effective separation of photogenerated charge carriers at the junction interface. Owing to its outstanding performance, graphene has already been used in combination with semiconductors for an enhancement of the photocatalytic performance [27,28]. Coupling graphene with g-C3N4 is regarded as an effective method for improving the conductivity and electrocatalytic performance of g-C3N4 [29,30].…”

Graphene-like 2D nanomaterial-based biointerfaces for biosensing applications

“…By virtue of inhibitory effects of forchlorfenuron on the catalase catalyzed H 2 O 2 reduction, electrochemical detection of forchlorfenuron with high sensitivity was also simultaneously realized. In another work, Shi et al reported the synthesis of graphene/C 3 N 4 hybrid, not only promoting the electron transfer ability of g-C 3 N 4 but also furnishing synergistic effect between graphene and g-C 3 N 4 (Gu et al 2015). They found that optimal amount of g-C 3 N 4 benefit the electrocatalytic activities for redox reaction and the electrochemical performances for the oxidation of several electroactive biomolecules were also greatly enhanced.…”
