“…At the same time, edible fruits are also suitable material for C-Dots synthesis. For example, Ramezani, Qorbanpour and Rahbar used quince fruit to synthesize C-Dots under microwave irradiation as an effective bioimaging agent for HT-29 cells under inverted fluorescence microscope at a concentration of 1,000 μg ml −1 (Ramezani et al, 2018). The synthesized C-Dots can be used in biosensors as well as in bioimaging due to low toxicity.…”

Carbon-Dots (C-Dots) have drawn much attention in recent years owing to their remarkable properties such as high biocompatibility, low toxicity, nano-scale size, and ease of modification with good tuneable photoluminescence performance. These unique properties have led C-Dots to become a promising platform for bioimaging, metal ion sensing and an antibacterial agent. C-Dots can be prepared using the top-down and bottom-up approaches, in which the latter method is commonly used for large scale and low-cost synthesis. C-Dots can be synthesized using sustainable raw materials or green biomass since it is environmentally friendly, in-expensive and most importantly, promotes the minimization of waste production. However, using biomass waste to produce high-quality C-Dots is still a matter of concern waiting for resolution, and this will be the main focus of this review. Fundamental understanding of C-Dots such as structure analysis, physical and chemical properties of C-Dots, various synthesis methodology and type of raw materials used are also discussed and correlated comprehensively. Additionally, factors affecting the bandgap of the C-Dots and the strategies to overcome these shortcomings are also covered. Moreover, formation mechanism of C-Dots focusing on the hydrothermal method, option and challenges to scale up the C-Dots production are explored. It is expected that the great potential of producing C-Dots from agricultural waste a key benefit in view of their versatility in a wide range of applications.

“…Highly stable and luminescent multi-color carbon quantum dots (~ 4.85 ± 0.07 nm) were produced in one pot using Cydonia oblonga powder as carbon precursors via microwave irradiation which have maximum emission intensity at 450 nm if excited at 350 nm with a quantum yield of 8.55%. Carbon quantum dots produced through microwave heating technique in 30 min were compared with those synthesized hydrothermally in a Teflon-linen stainless steel body autoclave at 200 °C (Ramezani et al 2018).…”

Carbon and graphene quantum dots are prepared using top-down and bottom-up methods. Sustainable synthesis of quantum dots has several advantages such as the use of low-cost and non-toxic raw materials, simple operations, expeditious reactions, renewable resources and straightforward post-processing steps. These nanomaterials are promising for clinical and biomedical sciences, especially in bioimaging, diagnosis, bioanalytical assays and biosensors. Here we review green methods for the fabrication of quantum dots, and biomedical and biotechnological applications.
