[ 1 ] - In Vitro Cytotoxicity of Two Subspecies of Juniperus excelsa on Cancer Cells

Objective(s) The cytotoxic effects of crude ethanol extracts of some previously tested Iranian conifers on tumor cell lines have motivated us to screen different parts of two subspecies in these genus. Materials and Methods Terminal branchlets and berries of Juniperus excelsa subsp. excelsa and J. excelsa subsp. polycarpos were collected, dried and extracted with ethanol/H2O (80/20 v/v) via pe...

[ 2 ] - One-pot synthesis of Ag/Fe3O4 nanocomposite: Preparation, characterization and efficient catalyst

In this study, nanometer sized of Ag/Fe3O4 nanocomposite (AFN) have been synthesized by using a simple and based on chemical reduction method. The size and shape of (AFN) controlled by using of condensation (Fe2O3 (2.975 mmol), NaBH4 (21.25 mmol), AgNO3 (2.532 mmol) and polyvinylpyrrolidone (PVP) (8.925 mmol K30 Mr=10.000) in 40 ºC. The synthesized AFN was characterized by XRD, scanning electro...

[ 3 ] - Biogenic Synthesis of Silver Nanoparticles Using Fruit Aqueous Extract of Psidium Guajava and Its Antibacterial Activity

One plant seed extract (Psidium guajava) was screened for their bioreduction behavior for synthesis of silver nanoparticles. Psidium guajava (PG) was found to exhibit the good reducing and protecting action in terms of synthesis rate and monodispersity of the prepared silver nanoparticles. UV–visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmis...

[ 4 ] - Preparation and characterization of friendly colloidal Hydroxyapatite based on natural Milk’s casein

Biocompatible hydroxyapatite nanocomposites are biocompatible, biodegradable and nontoxic have been paid many attentions as one of the most suitable vehicle for drug delivery use. Our objective in this work was to prepare and characterize caseins based HA nanocomposite in a colloidal form for drug delivery purposes. Casein biopolymer was firstly extracted from skimmed milk by adding acetic acid...
