Graphene quantum dot–based electrochemical biosensing for early cancer detection

Electrochemical biosensing systems coupled with graphene quantum dots (GQDs) have demonstrated suitability for cancer diagnostic strategies, particularly to identify the changes facilitating early phases of tumorigenesis as well detect ultralow concentrations biomarkers that distinguish between normal and malignant cells. GQDs, known a novel class zero-dimensional semiconductor nanocrystals, are tiny particles arranged in honeycomb structure size range 1–50 nm. The these GQDs is comparable biomolecules, thereby providing an ideal platform study biomolecules such proteins, cells, viruses. superior specific sensitive recognition biomarkers; they highly synergistic electrochemical sensors. This review will shed light on recent advancements made field GQD-based sensors detection, aim highlighting prospects further development diagnostics.
