“…They observed that folic acid could quench the fluorescence of the as-prepared CDs upon binding and employed those CDs as the selective probe for folic acid detection in the human urine [ 129 ]. The detection of Fe 3+ using fullerene (C60) derived CDs was demonstrated by Lan et al [ 130 ]. They passivated the CD surface with hydroxyl and carboxyl groups which interact with Fe 3+ , thereby quenching the fluorescence [ 130 ].…”

Carbon dots (CDs) are the new fellow of carbon family having a size less than 10 nm and attracted much attention of researchers since the last decade because of their unique characteristics, such as inexpensive and facile synthesis methods, easy surface modification, excellent photoluminescence, outstanding water solubility, and low toxicity. Due to these unique characteristics, CDs have been extensively applied in different kind of scientific disciplines. For example in the photocatalytic reactions, drug-gene delivery system, in vitro and in vivo bioimaging, chemical and biological sensing as well as photodynamic and photothermal therapies. Mainly two types of methods are available in the literature to synthesize CDs: the top-down approach, which refers to breaking down a more massive carbon structure into nanoscale particles; the bottom-up approach, which refers to the synthesis of CDs from smaller carbon units (small organic molecules). Many review articles are available in the literature regarding the synthesis and applications of CDs. However, there is no such review article describing the synthesis and complete application of CDs derived from small organic molecules together. In this review, we have summarized the progress of research on CDs regarding its synthesis from small organic molecules (bottom-up approach) via hydrothermal/solvothermal treatment, microwave irradiation, ultrasonic treatment, and thermal decomposition techniques as well as applications in the field of bioimaging, drug/gene delivery system, fluorescence-based sensing, photocatalytic reactions, photo-dynamic therapy (PDT) and photo-thermal (PTT) therapy based on the available literature. Finally, the challenges and future direction of CDs are discussed.

Natural‐Product‐Derived Carbon Dots: From Natural Products to Functional Materials

et al. 2017

Nature provides an almost limitless supply of sources that inspire scientists to develop new materials with novel applications and less of an environmental impact. Recently, much attention has been focused on preparing natural‐product‐derived carbon dots (NCDs), because natural products have several advantages. First, natural products are renewable and have good biocompatibility. Second, natural products contain heteroatoms, which facilitate the fabrication of heteroatom‐doped NCDs without the addition of an external heteroatom source. Finally, some natural products can be used to prepare NCDs in ways that are very green and simple relative to traditional methods for the preparation of carbon dots from man‐made carbon sources. NCDs have shown tremendous potential in many fields, including biosensing, bioimaging, optoelectronics, and photocatalysis. This Review addresses recent progress in the synthesis, properties, and applications of NCDs. The challenges and future direction of research on NCD‐based materials in this booming field are also discussed.

“…10,13,14 Carbon dots (CDs) as typical uorescent nanomaterials have received extensive attention due to their excellent properties, such as resistance to photobleaching, low toxicity, good biocompatibility and long-term stability, which have been extensively applied in biosensing and bioimaging. 15,16 Several CDs-based uorescent probes have been developed for Cu 2+ determination. However, it is still challenging to develop CDs-based biosensor because of poor selectivity of uorescent CDs.…”
