Abstract
Due to some environmental problems of sulfur compounds, it is necessary to eliminate these impurities from hydrocarbon fuels. To achieve effective removal of aromatic sulfur compounds such as benzothiophene and dibenzothiophene, different surface modification of carbon nanostructures, physical and chemical surface modifications, were utilized to reach the adsorptive desulfurization and oxidative desulfurization processes. The acid treatment by H2SO4/HNO3 and polymer-wrapping technique by polyethylene glycol were used for chemical and physical surface modification, respectively. Additionally, we tried to control the intensity and types of functional groups on the surface of carbon nanotubes. Besides, the efficiency of sulfur removal was measured. Both single-walled and multi-walled carbon nanotubes were utilized, and prepared samples have been investigated by FTIR, UV-Visible, TEM, Raman, and TGA techniques. The adsorption capacity values of each sample were evaluated by the temperature, time, and concentration parameters. The result shows that this surface modification can significantly improve the impurity removal of hydrocarbon fuel. Polymer-coated complexes showed higher removal values due to better dispersion than surface-oxidized carbon nanotubes. It was demonstrated that 90% of sulfur impurities with aromatic structure could be removed using an insignificant amount of the synthesized complex at moderate conditions. Besides, a comparison of laboratory data by conventional adsorption isotherms was investigated, and finally, the best operating conditions for maximum adsorbent performance were evaluated.

Magnetic Graphene Oxide Nanocarrier for Targeted Delivery of Cisplatin: A Perspective for Glioblastoma Treatment. Pharmaceuticals (Basel) 2019; 12:E76. [PMID: 31109098 PMCID: PMC6631527 DOI: 10.3390/ph12020076] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Revised: 05/10/2019] [Accepted: 05/16/2019] [Indexed: 12/19/2022] Open
Abstract
Selective vectorization of Cisplatin (CisPt) to Glioblastoma U87 cells was exploited by the fabrication of a hybrid nanocarrier composed of magnetic γ-Fe2O3 nanoparticles and nanographene oxide (NGO). The magnetic component, obtained by annealing magnetite Fe3O4 and characterized by XRD measurements, was combined with NGO sheets prepared via a modified Hummer's method. The morphological and thermogravimetric analysis proved the effective binding of γ-Fe2O3 nanoparticles onto NGO layers. The magnetization measured under magnetic fields up to 7 Tesla at room temperature revealed superparamagnetic-like behavior with a maximum value of MS = 15 emu/g and coercivity HC ≈ 0 Oe within experimental error. The nanohybrid was found to possess high affinity towards CisPt, and a rather slow fractional release profile of 80% after 250 h. Negligible toxicity was observed for empty nanoparticles, while the retainment of CisPt anticancer activity upon loading into the carrier was observed, together with the possibility to spatially control the drug delivery at a target site.

Potent in vitro antileishmanial activity of a nanoformulation of cisplatin with carbon nanotubes against Leishmania major. J Glob Antimicrob Resist 2018; 16:11-16. [PMID: 30244039 DOI: 10.1016/j.jgar.2018.09.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Revised: 09/09/2018] [Accepted: 09/12/2018] [Indexed: 12/20/2022] Open
Abstract
OBJECTIVES The aim of this study was to evaluate the cytotoxicity and antileishmanial activity of cisplatin-bonded carbon nanotubes both against promastigotes and amastigotes of Leishmania major in vitro. METHODS Cisplatin-bonded single-walled carbon nanotubes (CP-SWCNT) and cisplatin-bonded multi-walled carbon nanotubes (CP-MWCNT) were considered as test compounds. In addition, SWCNT, MWCNT, free cisplatin and meglumine antimoniate (Glucantime®) were considered as controls. The effect of each compound was evaluated both on promastigote and amastigote stages of L. major and the results were compared. RESULTS There was a statistically significant difference between the half-maximal inhibitory concentration (IC50) of CP-SWCNT and each of the controls, including SWCNT, cisplatin and Glucantime® (P<0.05). In addition, IC50 values of CP-MWCNT and each of the controls, including MWCNT, cisplatin and Glucantime®, were significantly different both for promastigotes and amastigotes (P<0.05). However, the selectivity index (SI) of CP-SWCNT was <10 (5.23), indicating that this compound is not completely safe. Moreover, the SI values of CP-MWCNT (12.54) and Glucantime® (16.28) were >10, indicating the selective effect of these two compounds on the parasite. Moreover, the IC50 of CP-MWCNT (0.11±0.09μM) for amastigotes was 41-fold lower than that of Glucantime® (4.52±1.31μM), suggesting that a lower dose of CP-MWCNT in comparison with Glucantime® is required to kill 50% of amastigotes. CONCLUSIONS According to the potent in vitro antileishmanial activity of CP-MWCNT at low concentration against L. major, we suggest that they are evaluated in an animal model.
