Copper Oxide Nano-Hydrogel Composite and their Toxicology Studies: A Green Chemistry Approach

The increasing demand for skin care products formulated with metal oxide nanoparticles such as Zinc oxide, Titanium oxide and Copper oxide nanoparticles calls for toxicological safety concerns. Phytochemical assisted synthesis of Copper oxide nanoparticles (CuONPs) has been achieved by a simple, one-pot chemical procedure using polyphenol-rich aqueous extract of Solanum torvum L. as a reducing and capping agent.

Synergistic Eeffect of Polyene Antifungals and Silver Nanoparticles Against Candida Parapsilosis

Candidiasis is a fungal infection caused by yeasts of the genus Candida spp. Among several pathogenic Candida species, we can highlight the C. parapsilosis due to susceptibility profile. Amphotericin B and nystatin are polyene antifungal drugs most frequently used to combat this type of infection. Silver nanoparticles (AgNPs) also have antifungal properties and can also provide synergistic action when combined with classic antifungals. Therefore, the aim of this study was evaluate the synergistic action of AgNPs, amphotericin B and nystatin against C. parapsilosis.

Formation of Gold Nanoprisms on Atomically Flat Mica Surface

A numerous methods are being used for synthesis of gold nanoparticles (NPs) in liquid media, in micelles and at different interfaces. The size and geometry of NPs depend on parameters of synthesis. Here we propose the growth of Au NPs on atomically flat mica surfaces. In such conditions the monocrystalline and isotropic NPs are being simultaneously formed on the surface.

Long Exposure to CdS-Dextrin Nanoparticles Induces an Immunomodulatory and Anti-Inflammatory Effect in Rats

Male Wistar rats were treated daily and intraperitoneally with CdS-Dextrin nanoparticles (100 μg/kg) during 30, 60, and 90 days. The effect of subacute and chronic administration of CdS-Dextrin nanoparticles on CD4/CD8 subpopulations of thymocytes, spleen-derived T cells, and peripheral blood CD4/CD8/CD3 T cells were analyzed by flow cytometer using a Rat T Lymphocyte Cocktail. An indirect ELISA kit analyzed cytokine Th1/Th2 levels. A DNA content and cell cycle analysis was carried out in bone marrow cells by flow cytometry. We also analyzed the presence of CdS-Dextrin nanoparticles in the thymus and spleen.

Investigation of Graphene Oxide in Diesel Soot

NanotechnologyAbstractIntroductionGraphene has emerged as a potential material in various scientific disciplines, ranging from material science, engineering, and more recently biomedicine. The paper describes the investigation of the presence of graphene and graphene oxide (GO) in the carbon soot of internal combustion diesel engines. The UV-Visible, Fourier transform infrared (FTIR), X- ray diffraction (XRD), Photoluminescent (PL) and Raman spectroscopic analysis of the sample provided a conclusive evidence of the formation of graphene and GO. The Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive Spectrum (EDX) of the sample show carbon nanoparticles (CNPs) of size less than 50nm.

Negatively Charged Gold Nanoparticles “Control” Double-Stranded DNAs Spatial Packing

We report here on new optic and small-angle X-ray scattering (SAXS) measurements concerning the formation of the dispersions from double-stranded (ds) DNA molecules, doped with negatively charged gold nanoparticles (nano-Au). The nano-Au fixation nearby the surfaces of linear ds DNA in solution of high ionic strength (0.3 M NaCl) and subsequent phase exclusion of (ds DNA-nano-Au) complexes from solution containing poly(ethylene glycol) results in decrease in the amplitude of abnormal negative band in the circular dichroism spectra of the formed cholesteric liquid-crystalline dispersions (CLCD).

Toxic Effect of Titanium (Tio2) on Wistar Rat (Rattus Norvegicus) Injected by Intravenously

Titanium dioxide (TiO2) (<100 nm) has been widely used in the production of paints, paper, and plastics, as well as in food additives and colorants .It has been classified as biologically inert in both humans and animals. Here we studied the toxicity of TiO2 on Wister rat. Main exposure area of NPs is caudal vein of Wistar rat.

SLNs Based on Co-Processed Lipids for Topical Delivery of Terbinafine Hydrochloride

Terbinafine hydrochloride (TH) is first line drug against treatment of onychomycosis; which is the commonest fungal infection of nail plate. However, strong barrier property of nail plate restricts the effective topical treatment of onychomycosis. In this study, TH loaded solid lipid nanoparticles (SLNs) were prepared and subsequently incorporated into a gel system. SLNs were prepared by high pressure homogenization (HPH) technique using glyceryl monosterate (GMS), compritol 888ATO and a co-processed lipid. They were evaluated for particle size, polydispersity index, zeta potential, % entrapment efficiency (%EE), % drug loading (%DL), drug content and in-vitro drug release. Optimized SLNs were incorporated into chitosan gel and further evaluated for in-vitro drug release and ex-vivo antifungal study.

Anodic Oxidation of Titanium in Sulphuric Acid and Phosphoric Acid Electrolytes

Anodisation of pure titanium has been carried out in sulphuric and in phosphoric acid solutions at potentials ranging from 50 to 150V. The SEM and AFM morphological analysis indicates that, within this potential range, oxidation in sulphuric acid solution produces better developed mesoporous oxide layers.
