FePt/iron oxide core/shell nanoparticles are synthesized by a two step polyol process with 1,2hexadecanediol as the reducing reagent. Monodispersed 2.6-nm FePt nanoparticles are first obtained by reduction of iron(III) acetylacetonate and platinum(II) acetylacetonate. These preformed FePt nanoparticles are then used as seeds and an iron oxide shell is formed in the second synthesis step. The ro...

we have used tungestophosphoric acid to catalyze oxidative amidation reaction from benzyl alcohols and methylarens with hydrochloride salts of amines. to achieve this purpose, modified magnetic nanoparticles (γ-fe2o3@sio2@h3pw12o40) were applied as catalyst and tbhp as external oxidant. after optimizing, different derivates of benzamides were synthesized in good yields. also, the result of two ...

quick identification of vibrio cholerae in epidemics is   important, on the other hand; conventional methods are time-consuming and   costly. the aim of this study was to develop a rapid, inexpensive and high   sensitivity method for quick identification of vibrio cholerae . for   this purpose we designed a pcr detection based on magnetic nanoparticles for   identification of bacterial dna by p...

magnetic lignocellulosic fibers have good potential in applications such as information storage, security papers, electromagnetic shielding and etc. in this study unbleached bagasse fibers were used to fabricate magnetic paper by chemical co-precipitation method. lumen loading and precipitation of magnetic nanoparticles on the surface of fibers were carried out by in situ synthesis. then the fo...

Biofilm infections are extremely hard to eradicate and controlled, triggered and controlled drug release properties may prolong drug release time. In this study, the ability to externally control drug release from micro and nanoparticles was investigated. We prepared micro/nanoparticles containing ciprofloxacin (CIP) and magnetic nanoparticles encapsulated in poly (lactic-co-glycolic acid) PLGA...
