and biological materials. It has been found that fluorescent probes are one of the most successful approaches. Fluorescent probes such as organic molecules have the advantages of high sensitivity and fast analysis, but they suffer from low water solubility. Semiconductor quantum dots (QDs) can be used as fluorescent probes, while the issue of toxicity limits their practical applications [1,2]. Fluorescent carbon dots (CDs) with similar physicochemical properties of QDs and relatively low in toxicity and cost of synthesis are the most suitable alternatives to organic molecules and QDs [3]. CDs gradually become a rising star as fluorescent probes in a number of fields [4,5]. CDs, a new member of carbon nanomaterial family with diameter below 10 nm, have great fluorescent performance, excellent dispersity and biocompatibility [6,7]. The synthetic methods of CDs can be classified into top-down and bottom-up approaches [8].Top-down methods rely on reducing the size of the graphite-like structures until the products become fluorescent nanoparticles. In the bottom-up processes, anything with carbogenic nature can synthesize CDs under suitable conditions [9]. Always the synthetic strategies and the precursors affect the internal properties of the resulting nanoparticles such as the size, crystallinity, oxygen or nitrogen content, emission characteristics and compatibility with a particular solvent [10][11][12][13]. Particularly, with the advantages of great dispersibility in water and tunable fluorescence, CDs are also becoming attractive alternatives for novel fluorescence markers, fluorescent probes and optical probes [14,15].In this review, we mainly summarize the recent advances of CDs about the easy synthesises, sensitive fluorescent detections of ions and organic molecules and possible detection mechanisms. It is our aim that the synthesis of this knowledge will offer valuable insight and inspire research into the exciting areas. Some suggestions and an outlook are put forward about the applications of CDs.Abstract Carbon dots (CDs), a new class of fluorescent materials, have recently attracted considerable research interest. CDs have overcome some defects of traditional nanomaterial. In addition to their small size and optical properties, CDs have the excellent advantages of good biocompatibility and are easy to achieve surface functionalization. Since this discovery, CDs can be widely used in the field of biochemical sensing and environmental testing. This article reviews the progress in the research and development of CDs on their syntheses, applications for the fluorescence detection and possible mechanisms. Finally, we have an outlook of the research trends and future prospects of CDs.

Carbon dots (CDs) are a recently discovered class of fluorescent nanomaterials with great potential to be applied in the analytical field. CDs have demonstrated to be a promising alternative to conventional organic fluorophores or quantum dots as optical nanoprobes for sensing different chemical species. In this overview, we review the progress in the design of novel nanoprobes based on fluorescent CDs for inorganic trace analysis. Representative examples of CD-based assays are described and the different sensing strategies are discussed.
