“…Carbon-based nanomaterial has pulled in more interest for late years. There are extensive variety of carbon nanostructures have been synthesized, for example, carbon nanotubes, fullerenes, Nano fibers, Nano diamond, carbon nanoparticles, and different carbonaceous nanomaterial [1]. Carbon nanoparticles (CNPs), which assign to the type of round carbon-related nanomaterial, display numerous superior optical characteristics, such as stabilized photoluminescence property (PL), wide excitation wavelengths (λex) and tunable radiation.…”

“…Synthesis of carbon-metallic nanocomposites and their use in the biomedical field has been reported previously. [35][36][37][38] Such synthetic strategies include PEGylation, a process that involves the passivation of the surface of nanoparticles by polyethylene glycol (PEG), to enhance their dispersion and solubility in aqueous solutions. 39,40 It has been reported that the interaction of the reticuloendothelial system, ie, macrophages and monocytes with PEGylated nanoparticles decreases, and their circulation time in blood increases.…”

The combination of chemotherapy and photodynamic therapy has emerged as a promising strategy for cancer therapy due to its synergistic effects. In this work, PEGylated silver nanoparticles decorated with graphene quantum dots (Ag-GQDs) were tested as a platform to deliver a chemotherapy drug and a photosensitizer, simultaneously, in chemo-photodynamic therapy against HeLa and DU145 cancer cells in vitro. Ag-GQDs have displayed high efficiency in delivering doxorubicin as a model chemotherapy drug to both cancer cells. The Ag-GQDs exhibited a strong antitumor activity by inducing apoptosis in cancer cells without affecting the viability of normal cells. Moreover, the Ag-GQDs exhibited a cytotoxic effect due to the generation of the reactive singlet oxygen upon 425 nm irradiation, indicating their applicability in photodynamic therapy. In comparison with chemo or photodynamic treatment alone, the combined treatment of Ag-GQDs conjugated with doxorubicin under irradiation with a 425 nm lamp significantly increased the death in DU145 and HeLa. This study suggests Ag-GQDs as a multifunctional and efficient therapeutic system for chemo-photodynamic modalities in cancer therapy.

Fullerenes synthesis by combined resistive heating and arc discharge techniques

2016

The two main electrode techniques for fullerenes production; the direct arc technique and the resistive heating of graphite rod were employed in this work. One of the electrodes was resistively heated to high temperature and subjected to arc discharge along its length by the second graphite rod. Fullerenes solid were extracted from carbon soot samples collected from an installed arc discharge system using the solvent extraction method. The fullerenes solid obtained from carbon soot collected for 2 min of arc discharge run when one of the electrodes was resistively heated at different voltages all gave higher yields (maximum of 67 % higher, at 150 A arc current and 200 Torr chamber pressure) compared to when no resistive heating was carried out. Scanning electron microscopy and ultraviolet visible spectroscopy analysis carried out on all fullerenes solid indicated the presence of fullerenes. The enhancement of fullerenes production by combined resistive and direct arc techniques shows prospect for possible use at industrial level for large scale production.
