“… 15 For instance, Islam et al , 16 prepared fullerene-C60 stabilized Au nanoparticles supported on titanium dioxide and used as an efficient catalyst for the degradation of methyl orange and reduction of 4-nitrophenol. Similarly, Ko and co-workers 17 demonstrated catalytic reduction of 4-nitrophenol using Au-nanoparticle/Fullerene-C60 composites. In spite of that only a limited number of papers published on the carbon fullerene-C60 supported transition metal nanoparticles for catalytic organic conversions.…”

“…The filter paper was used to separate the cold mixture, and the precipitate was then dried for three hours at 120°C in the oven. 14 Loading of Fullerene with Pemetrexed and Nickel Nanoparticles (NiNPs) 80 mg of the previously synthesized C60 fullerene and 25 mL of benzene were added to a 100 mL Erlenmeyer flask. The reaction mixture was exposed to ultrasonication for 60 minutes after being agitated for 30 minutes.…”

Objective: This study aims to create a new delivery system for pemetrexed, employing a metal-C60 fullerene combination for the first time. Additionally, a lung cancer cell line study will be used to examine the impact of this combination on the release, behavior, and drug’s cytotoxicity. Methods: To utilize a laser to irradiate hydrocarbons, fullerene C60 (Buckysomes) was produced and then nanosized by adding different volumes of isopropyl alcohol and ultrasonication. Gold Nanoparticles (AuNPs) and nickel nanoparticles (NiNPs) were also prepared each one separately and added to the previous mixture together with Pemetrexed (PMX) with further ultrasonication for 20 minutes. The mixture is kept in the refrigerator for 20 hours and then filtered. The precipitate was dried and characterized for particle size, invitro release, and anticancer activity in comparison to pemetrexed loaded on C60 fullerene previously prepared in our laboratory. Results: The evaluation techniques revealed the successful loading of pemetrexed on metals- fullerene C60 nanocarrier, SG10 was the optimum sample with % of yield reach to 95.36. The release profile shows that the percentage release of pemetrexed after 240 minutes is equal to 40% from pure PMX, while the release after 240 minute was found to be 87.8 % from pemetrexed loaded gold nanoparticles (AuNPs) fullerene C60 nanocarrier (SG10), while NiNPs not significantly improved the release profile of Pemetrexed from Pemetrexed loaded NiNPs – fullerene (SN7). Pemetrexed loaded on gold nanoparticles (AuNPs), when compared to pure PMX (3.1 M) and SN7 (11.5 M), fullerene nanocarrier (SG10) exhibits a lower IC50 (1.55 M) and a greater cytotoxic effect (high IR percent) on A549 cancer cells. Pemetrexed’s cytotoxicity in A549 was enhanced after being loaded onto gold nanoparticles (AuNPs)-fullerene nanocarriers (90.4% cell death for SG10) as opposed to pure drug (60% cell death). This finding suggests that the loading process enhanced the drug’s cytotoxic activity for the tumor cells, which may have sped up the onset of action (30% cell death after 24 hours). Conclusion: This study successfully prepared Metals- fullerene C60 Buckysomes loaded with pemetrexed utilizing gold and nickel, which may serve (especially Au- fullerene) as a suitable nanocarrier for pemetrexed, resulting in an improvement to solubility, the release pattern, and cytotoxicity.

“…In addition, CuS nanoparticles have shown outstanding photodegradation and quick dye adsorption capabilities for organic dyes in aqueous solution [2]. Recently, interest in C 60 fullerene nanowhiskers has increased due to their distinct chemical and physical characteristics, as well as potential uses in materials like catalysis and photocatalysis [18][19][20][21][22][23][24][25]. The C 60 fullerene nanowhiskers of the needle-like crystals were prepared by the liquid-liquid interfacial precipitation (LLIP) method using a C 60 -saturated toluene and isopropyl alcohol [26].…”

The liquid-liquid interfacial precipitation (LLIP) approach was used to synthesize the C60 fullerene nanowhisker (FNW)–CuS nanoparticle composites utilizing a CuS nanoparticle solution, C60-saturated toluene, and isopropyl alcohol (IPA). Powder X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) were used to characterize the product of C60 FNW–CuS nanoparticle composites. These were also utilized to photocatalytic degradation of rhodamine B (RhB) under blue light emitting diode (LED) irradiation at 450 nm. Also, UV–vis spectroscopy was used to confirm the photocatalytic degradation activity of RhB over the C60 FNW–CuS nanoparticle composites. The percentage of photocatalytic degradation of RhB was shown to be 95.148%. The kinetics study for photocatalytic degradation of RhB using C60 FNW–CuS nanoparticle composites followed a pseudo-first-order reaction rate law. C60 FNW–CuS nanoparticle composites as photocatalyst have a rate constant of 4.82×10-2 min-1 at 25 °C.
