objective: the label and detection of cells injected into target tissues is an area of focus for researchers. iron oxide nanoparticles can be used to label cells as they have special characteristics. the purpose of this study is to examine the effects of iron oxide nanoparticles on human-derived amniotic membrane stem cell (hamcs) survival and to investigate the magnetic properties of these nan...

background: increased impervious surfaces in urban areas not only increase runoff volume and peak flow, but also worsen urban storm water pollution. the polluted runoff has many adverse impacts on human life and environment. the purpose of this study was to investigate and compare the efficiency of sand columns coated with nanoparticles of iron oxide in the presence and absence of a magnetic fi...

Present review article describes main causes of chronic kidney disease a major health problem public health problem round the globe. Disease has multiple etiologies related to sequential pathophysiological stages. It has major concern with chronic changes in renal structure and that severely alter glomerular filtration rate in patients. This article explains CKD biomarkers in brief i.e., serum ...

We report the preparation of magnetic mesoporous silica (MMS) nanoparticles with the potential multifunctionality of drug delivery and magnetic hyperthermia. Carbon-encapsulated magnetic colloidal nanoparticles (MCN@C) were used to coat mesoporous silica shells for the formation of the core-shell structured MMS nanoparticles (MCN@C/mSiO2), and the rattle-type structured MMS nanoparticles (MCN/m...

Multimodal Gold-speckled silica nanoparticles as contrast agents for noninvasive imaging with magnetic resonance imaging and photoacoustic tomography have been prepared in a simple one-pot synthesis using nonionic microemulsions. Magnetic resonance contrast is provided through gadolinium incorporated in the silica matrix, whereas the photoacoustic signal originates from nonuniform, discontinuou...

Although iron oxide magnetic nanoparticles (MNP) have been proposed for numerous biomedical applications, little is known about their biotransformation and long-term toxicity in the body. Dimercaptosuccinic acid (DMSA)-coated magnetic nanoparticles have been proven efficient for in vivo drug delivery, but these results must nonetheless be sustained by comprehensive studies of long-term distribu...

Preparation of magnetic nanoparticles coated with chitosan (CS-coated Fe3O4 NPs) in one step by the solvothermal method in the presence of different amounts of added chitosan is reported here. The magnetic property of the obtained magnetic composite nanoparticles was confirmed by X-ray diffraction (XRD) and magnetic measurements (VSM). Scanning electron microscopy (SEM) and transmission electro...

Magnetic silica nanoparticles modified by a chiral selector were demonstrated to be useful in magnetic field induced separation of enantiomers.

We report the synthesis of Fe3O4@mSiO2 nanostructures of different meso-silica (mSiO2) shell thickness, their biocompatibility and behaviors for loading and release of a model drug ibuprofen. The composite nanostructures have superparamagnetic magnetite cores of 208 nm average size and meso-silica shells of 15 to 40 nm thickness. A modified Stöber method was used to grow the meso-silica shells ...

We present a systematic study on the preparation, characteration and potential application of Fe3O4 and Fe3O4@SiO2 nanoparticles. Fe3O4 nanoparticles of controllable diameters were successfully synthesized by solvothermal system with tuning pH. The magnetic properties of nanoparticles were measured by vibration sample magnetometer. Fe3O4@ SiO2 nanoparticles were obtained via classic Stöber proc...
