Graphene nanoribbons: A cutting-edge material for the point-of-care cancer biomarker detection
Year: 2025
Type: article
Abstract: Graphene nanoribbon (GNRs), being quasi-one-dimensional strips of single-layer graphene, are a fascinating material among the others in the graphene family due to their unique edge and width-oriented semiconducting properties. Possible to be formed using both the top-down and bottom-up synthesis routes, GNRs are available in numerous forms, including zig-zag, armchair, chiral, chevron, cove, and gulf structures, each resulting in an exceptional set of physicochemical properties suitable for a variety of specific applications. Recent research has shown the exceptional applicability of GNRs in the biomedical field, since the possibility of covalent and non-covalent functionalization of GNRs generates an excellent platform for the immobilization of biological molecules and their biosensing, also those present in ultra-low quantities. This systematic review aims to present the potential of GNRs in the field of the electrochemical detection of cancer biomarkers, which should be identified as early as possible for the accurate diagnosis and prognosis. After providing a concise introduction to GNRs, including their classification, properties, and synthesis routes, this review discusses recent developments in GNRs-based point-of-care detection methods, highlighting their great potential in biosensing and enlightening their prospects in future research.
