Excessive consumption of substances such as food colorants, exposure to doses of metal
ions, antibiotic residues and pesticides residues above maximum tolerance limit have a
detrimental effect on human health. Hence in detecting these harmful substances, the
development of sensitive, selective and convenient analytical tools is an essential step.
Graphene and graphene like 2D graphitic carbon nitride have shown great promise in the
development of electrochemical sensors for determining the levels of these substances in …
