Carbon has always found a spotlight in human life either in the form of graphite, diamonds, activated charcoal, carbon nanotubes, or carbon dots (CDs). Carbon quantum dots (CQDs) or CDs became the centre of attraction because of their potential applications in biomedical field such as bio‐imaging, drug nanocarriers, gene therapeutics, photosensitizing agents, theranostics and provides other multifunctional diagnostic platforms. There are numerous advantages of CDs due to their biocompatibility, reduced toxicity, water‐solubility, ease of scale‐up, and, most notably their fluorescence properties contrary to other carbon nanostructures. In last few years, significant efforts have been put by various research teams to synthesize and develop nanostructured materials possessing specific functional properties and characteristics. This work focus on the recent developments in the synthetic approaches applied for CDs using environment‐friendly sources. This review also highlights the mechanistic aspects, applications of CDs in biomedicine and a multi‐sensing platform along with challenges and future perspectives of this promising field. The authors believe that this review will help audible researchers to select a suitable environment‐friendly approach for the synthesis of CDs from green sources with required functions and properties. It will also guide researchers to develop a more convenient, efficient, and environment‐friendly method for the synthesis of new tunable carbon dots.

“…Molecularly imprinted polymers (MIPs) are synthetic material, which can be prepared according to different requirements (Venkatesh et al, 2017). Many results showed that the affinities and selectivities of MIPs are similar to those of natural biomolecular recognition systems (Altintas et al, 2015;Jiang, He, Gong, Gao, & Xu, 2019;Wang, Jiang, Ju, Qiao, & Xu, 2018). More importantly, MIPs have stable physical and chemical properties and can be used in a variety of complex environments.…”

“…However, due to excessive and unreasonable use, it has become one of the main pollutants in crops, most likely resulting in food poisoning caused by the entry of trace trichlorfon residues into the human body . To prevent the negative impact of trichlorfon on human health and provide consumers with safe crop products, many traditional methods have been used to detect organophosphorus compounds such as chromatography, fluorescence measurements, capillary electrophoresis, and surface plasmon resonance . However, to some extent, the application of these technologies is limited because of the expense of the instruments and the complexity of the operation.…”

By combining the controllable core/shell strategy with graft copolymerization of polysaccharides, controllable core/shell magnetic molecularly imprinted polymers (MIPs) based on konjac glucomannan for selective recognition and enrichment of trichlorfon were fabricated and evaluated. By varying the dose of the polymeric precursors, the shell thickness of the core/shell structure could be regulated over a wide range. The magnetic nanoparticles encapsulated by polymers still had high magnetic performance and could be easily separated by an external magnetic field. The results of adsorption experiments showed that the MIPs could specifically recognize and adsorb trichlorfon with excellent selectivity, repeatability, and stability. The adsorption isotherm of MIPs could be fitted by the Langmuir equation. In addition, magnetic MIPs have been successfully applied to the detection of trichlorfon in real samples. Eco-friendly MIPs would be particularly suitable for the enrichment and separation of pesticide residues in food samples.
