“…Their non-toxicity is a key advantage to perform in vivo [118][119][120][121][122] and in vitro [41,67,113,[123][124][125] bioimaging experiments and drug delivery experiments [126]. Indeed, the range of applications of CDs is surprisingly wide: for example, antiviral [127,128] and antibacterial [129] properties of CDs were recently discovered, and CDs were even used as nanoweapons against mosquitos [130], or as a component of fluorescent inks [53,89]. So far, the majority of CDs-based devices have been developed and tested just in a laboratory environment.…”

Carbon Nanodots: A Review—From the Current Understanding of the Fundamental Photophysics to the Full Control of the Optical Response

Carbon dots (CDs) are an emerging family of nanosystems displaying a range of fascinating properties. Broadly speaking, they can be described as small, surface-functionalized carbonaceous nanoparticles characterized by an intense and tunable fluorescence, a marked sensitivity to the environment and a range of interesting photochemical properties. CDs are currently the subject of very intense research, motivated by their possible applications in many fields, including bioimaging, solar energy harvesting, nanosensing, light-emitting devices and photocatalyis. This review covers the latest advancements in the field of CDs, with a focus on the fundamental understanding of their key photophysical behaviour, which is still very debated. The photoluminescence mechanism, the origin of their peculiar fluorescence tunability, and their photo-chemical interactions with coupled systems are discussed in light of the latest developments in the field, such as the most recent results obtained by femtosecond time-resolved experiments, which have led to important steps forward in the fundamental understanding of CDs. The optical response of CDs appears to stem from a very complex interplay between the electronic states related to the core structure and those introduced by surface functionalization. In addition, the structure of CD energy levels and the electronic dynamics triggered by photo-excitation finely depend on the microscopic structure of any specific sub-type of CD. On the other hand, this remarkable variability makes CDs extremely versatile, a key benefit in view of their very wide range of applications.

“…Therefore, during the hydrolysis process, an aqueous extract of the material decomposes carbohydrate molecules and forms surface-functionalized circumstances by generating different functional groups, such as hydroxyl, carbonyl, carboxyl and epoxy groups, in the solution mixture. 10 This process helps to liberate a substantial amount of protons and electrons to reduce the metal ions. 34 Cyprus rotundas contains more than 35% carbohydrate content.…”

“…Vani and Brindhaa (2013) reported that nanoparticles are more reactive than their bulk counterpart because of their increased surface to volume ratio. The toxicity of nanoparticles may be due to partial lysis of the midgut epithelial cells; vesicles and damaged membranes at the apical side of epithelial cells (Foldbjerg et al 2015;Sultana et al 2018). Moreover, nanoparticles caused death in insects by being absorbed into the cuticular lipids causing physical damage (Barik et al 2008).…”

Green synthesized nanoparticles have been studied as new and more effective biopesticides against insects of medical importance and this for their eco-friendly aspects. In the current study Moringa oleifera leaf extract (Mo-LE) was used to synthesis silver nanoparticles (Mo-AgNPs) and zinc oxide nanoparticles (Mo-ZnONPs). Low concentrations of MoLE , Mo-AgNPs and Mo-ZnONPs showed the larvicidal and pupicidal toxicity against Musca domestica. In larvicidal bioassay, the values of LC 50 were 16.50, 2.03 and 6.41 mg/ml for MoLE , Mo-AgNPs and Mo-ZnONPs, respectively. In addition, the LC 50 was determined against pupae, which were129.77, 9.604 and 17.10 mg/ml for MoLE , Mo-AgNPs and Mo-ZnONPs, respectively. Moreover, treatment larvae with LC 50 's of MoLE , Mo-AgNPs and Mo-ZnONPs produced a significant reduction (P<0.05) in the fecundity of female and a highly significant reduction (P<0.01) in the egg hatchability. The total protein content and activities of nonspecific esterases, acetylcholine esterase, and glutathione S-transferase enzymes were significantly declined after larvae had fed on LC 50 Mo-AgNPs and Mo-ZnONPs treated diets as compared with the control. This study indicates that it is feasible to use M. oleifera synthesized nanoparticles as effective candidates to develop newer and cheap control tools for immature stages of M. domestica. 100 ml water) as a surface to lay eggs. The culture was maintained at 27°C in 60-70% relative humidity, with a 16 L:8 D h photoperiod. Plant Material: Fresh green leaves of M. oleifera were collected from the garden of
