BACKGROUND 5-Fluorouracil (5-FU) is one of the most classic chemotherapy drugs. Nanoparticle drug delivery vehicles offer superiority over target effect enhancement and abatement of side effects. Little is known however as to the specific effect of nanoparticle on peritoneal dissemination of colon cancer. The aim of this study is to prepare one NPs (nanoparticles) loaded with 5-FU and investiga...

limn2o4 spinel cathode materials have been successfully synthesized by solid-state reaction. surface of these particles were modified by nanostructured lifepo4 via sol gel dip coating method. synthesized products were characterized by thermally analyzed by thermogravimetric and differential thermal analysis(tg/dta), x-ray diffraction (xrd), scanning electron microscopy (sem), and energy dispers...

Synthesis of cerium oxide (CeO2) nanoparticles (NPs) via biological approach has received a lot interest to reduce the harmful effects chemical synthesis. In present study, Colocasia esculenta leaf extract facilitated preparation CeO2-NPs by using sol-gel technique. The crystal structural was proven X-ray powder diffraction (XRD) investigation be cubic with size 2.94 nm according Debye–Scherrer...

BACKGROUND This study aims to investigate the influence of different stirring time for synthesis of silver nanoparticles in glutathione (GSH) aqueous solution. The silver nanoparticles (Ag-NPs) were prepared by green synthesis method using GSH as reducing agent and stabilizer, under moderate temperature at different stirring times. Silver nitrate (AgNO3) was taken as the metal precursor while A...

Human serum albumin nanoparticles (HSA-NPs) were synthesized using the modified desolvation method. Fourier transform infrared spectroscopy (FT-IR), electronic absorption spectroscopy (UV-Vis), Zeta Sizer as well as field emission scanning electron microscope (FE-SEM) of the sample confirmed the formation of HSA NPs with an average size of 68 nm. The obtained results shown that HSA-NPs was succ...

Background: Nanoparticles (NPs) are colloidal systems with particles ranging from 10 to 100 nm in diameter. Because of their large surface-volume ratio, NPs are biologically active materials that could interact with biomolecules and microorganisms, enter into the cells, and affect the metabolic functions. The study aimed to biosynthesize silver nanoparticles (Ag-NPs) from Capparis spinosa fruit...

Platinum nanoparticles (Pt NPs) have structural properties that differ from their bulk forms, such as physical and chemical properties. The cost toxicity problems caused by the synthesis of Pt NPs, which are widely used in biomedical fields, laser ablation, aerosol, sol-gel, co-precipitation, reduction techniques eliminated biological method. In this study, biosynthesis Cetraria islandica extra...

Multipodal nanoparticles (NPs) with controlled tethers are promising principal building blocks, useful for constructing more complex materials, much like atoms are connected into more complex molecules. Here we report colloidal sphere templating as a viable means to create tetrapodal NPs with site-specific tethers. Amorphous sol-gel materials were molded by the template into shaped NPs that mim...
