RETRACTED: Optical bio(sensing) using nitrogen doped graphene quantum dots: Recent advances and future challenges
Abstract The exceptional optical properties and the presence of high number of reactive sites make nitrogen doped graphene quantum dots (N-GQDs) powerful tools in analytical nanoscience and nanotechnology. At the same time, their opto-electronics properties make them excellent nanomaterials for biomedical analysis aspects. This review aims to explore progress to date various features of N-GQDs for optical bio (sensing) of target analytes. Moreover, as another aim of this review is to provide insight into the intensity based spectroscopic methods which are applied in bio (sensing) discussing their advantages and disadvantages. More importantly, we discuss in detail different aspects of the a…
