“…Frankincense is an oleo gum resin derived from the Boswellia species, traditionally used to treat many diseases, mostly those dealing with memory functions [ 75 ]. Al Washahi et al [ 76 ] recently established a green synthesis method of biogenic AuNPs from chloroauric acid (HAuCl 4 ) using frankincense resin via microwave irradiation. The frankincense resin was composed of hydroxyl and carbonyl groups responsible for the synthesis and stabilization of AuNPs.…”

“…Given the vital roles of Cu 2+ ions in biological and environmental systems, many fluorescent probes for Cu 2+ detection have been reported, such as naphthalimide, 5 pyrene, 6 and AuNPs. 7 However, their selectivity, biocompatibility, and sensitivity need to be further improved to be more suitable for environmental applications. Carbon dots (CDs) are a pioneering type of carbon-derived nanostructure with fascinating characteristics, including excellent optical stability, multifunctionality, tunable fluorescence, and low toxicity.…”

Monitoring the copper ion (Cu 2+ ) levels has attracted considerable attention due to its significance in environmental and physiological applications. Here, we report on red dualemission carbon dots (CDs) with a 43% quantum yield and without excitation wavelength dependence for probing Cu 2+ in vitro and in vivo. The solid coordination of Cu 2+ with the surface groups of CDs generates an asynchronous fluorescent quenching of CDs and enables ultrasensitive detection of Cu 2+ in vitro. The intensity ratio of fluorescence at 605 and 650 nm (F 605 /F 650 ) shows a linear response to Cu 2+ concentration ranging from 0 to 1.1 μM, with an ultralow detection sensitivity of 0.58 nM. Moreover, the asprepared CDs show good stability, anti-interference capability, low cellular toxicity, and exceptional ability to penetrate plant cell walls, endowing the CDs with excellent bioimaging potentials and tracking the dynamic levels of Cu 2+ in living cells.

“…The toxicity problem can be solved by using organic plant materials as stabilizing and capping agents and techniques for making nanoadsorbents that are safe for the environment [34,35]. We previously described the synthesis of Au and Pd nanoparticles from frankincense resin and the efficiency of these particles in catalyzing dye degradation [36,37].…”

Aquatic pollution, which includes organic debris and heavy metals, is a severe issue for living things. Copper pollution is hazardous to people, and there is a need to develop effective methods for eliminating it from the environment. To address this issue, a novel adsorbent composed of frankincense-modified multi-walled carbon nanotubes (Fr-MMWCNTs) and Fe3O4 [Fr-MWCNT-Fe3O4] was created and subjected to characterization. Batch adsorption tests showed that Fr-MWCNT-Fe3O4 had a maximum adsorption capacity of 250 mg/g at 308 K and could efficiently remove Cu2+ ions over a pH range of 6 to 8. The adsorption process followed the pseudo-second-order and Langmuir models, and its thermodynamics were identified as endothermic. Functional groups on the surface of modified MWCNTs improved their adsorption capacity, and a rise in temperature increased the adsorption efficiency. These results highlight the Fr-MWCNT-Fe3O4 composites’ potential as an efficient adsorbent for removing Cu2+ ions from untreated natural water sources.
