Design strategies of carbon nanomaterials in fluorescent sensing of biomolecules and metal ions -A review

Abstract

Exceptional optical properties of nano-carbon have facilitated researchers to construct surplus of carbon nanomaterials in the field of fluorescent sensing adopting various sensing strategies. It would be effortless for nano-researchers to fabricate a sensor by disentangling those sensing strategies as there were no systematic reviews about sensing strategies reported till date. Hence the focus of this review is to diligently scrutinize to furnish a perspicuous view on sensing strategies adopted by carbonic nanomaterials such as Graphene quantum dots (GQDs), Carbon dots (CDs), Carbon nanotubes (CNTs), Graphene oxide (GO) and graphitic Carbon nitride (g-C3N4) especially in detection of metal ions and bio related analytes. This could pave way for facile fabrication of sensor to achieve detection of specific target. Finally, review is summarized with plausible ways to revamp those materials to reinforce its sensing performance.
