For ultrasensitive magnetic resonance imaging (MRI), magnetic nanoparticles with extremely high r2 relaxivity are strongly desired. Magnetosome-like nanoparticles were prepared by coating polyethylene glycol-phospholipid (PEG-phospholipid) onto ferrimagnetic iron oxide nanocubes (FIONs). FIONs exhibited a very high relaxivity (r2) of 324 mM(-1) s(-1), allowing efficient labeling of various kind...

Application of Magnetic Nanoparticles (MN) has emerged as a potential mode of hyperthermia, a modality for cancer therapy, in which temperature of a tumor is increased beyond physiological temperature up to 40-43 °C. We have prepared Fe 3 O 4 magnetic nanoparticles (Fe 3 O 4 -MN), which were surface-functionalized with polyethylene glycol (Fe 3 O 4 -PEG-MN) and oleic acid (Fe 3 O 4 -OAMN) to ma...

Osteoporosis is a result of imbalance between bone formation by osteoblasts and resorption by osteoclasts (OCs). In the present study, we investigated the potential of limiting the aggravation of osteoporosis by reducing the activity of OCs through thermolysis. The proposed method is to synthesize bisphosphonate (Bis)-conjugated iron (II, III) oxide (Fe3O4) nanoparticles and incorporate them in...

The evacuant solution (ES) is a drug that has been used to clean the colon. The most common described side effects when using this drug are abdominal symptoms; skin rash is rare. We report on two patients who presented urticaria and angioedem after the intake of an evacuant solution to make a rectoscopy. We performed allergy studies: skin prick tests with common inhalants, pure ES and the compo...

The aim of the present study was assessment sub-chronic effects silver (AgNPs) and gold nanoparticles (AuNPs) 40 nm primary size either stabilised with citrate (CIT) or coated polyethylene glycol (PEG) on freshwater invertebrate Gammarus fossarum. Silver nitrate (AgNO3) used as a positive control in order to contribution ions potentially released from AgNPs observed effects. A multibiomarker ap...

The physicochemical properties of Doxorubicin–PEG–FOL and Daunorubicin-PEG-FOL ( Doxorubicin and Daunorubicin conjugated to polyethylene glycol–folate nanoparticles) have been estimated using Density functional Theory (DFT) and Hartree Fock(HF) calculations.In this report some geometrical parameters of Doxorubicin-PEG-FOL complex of the conjugated complex and Daunorubicin–PEG–FOL complex of the...

To enhance tumor magnetic resonance imaging (MRI) signals via the selective accumulation of contrast agents, we prepared folate-modified gadolinium-lipid-based nanoparticles as MRI contrast agents. Folate-modified nanoparticles were comprised of polyethylene glycol (PEG)-lipid, gadolinium diethylenetriamine pentaacetic acid lipid, cationic cholesterol derivatives, folate-conjugated PEG-lipid, a...

We herein report the development of multifunctional folic acid (FA)-targeted Fe3O4 @ Au nanostars (NSs) for targeted multi-mode magnetic resonance (MR)/computed tomography (CT)/photoacoustic (PA) imaging and photothermal therapy (PTT) of tumors. In this present work, citric acid-stabilized Fe3O4/Ag composite nanoparticles prepared by a mild reduction route were utilized as seeds and exposed to ...

The objective of this study was to optimize the physicodynamic conditions of polymeric system as a coating substrate for drug eluting stents against restenosis. As Nitric Oxide (NO) has multifunctional activities, such as regulating blood flow and pressure, and influencing thrombus formation, a continuous and spatiotemporal delivery of NO loaded in the polymer based nanoparticles could be a via...

Membranes have been developed by coating a blend of chitosan (CS) and polyethylene glycol (PEG) of different molecular weights (4000, 10,000 and 20,000) on cotton fabric followed by freeze drying. The influence of PEG molecular weight on the physical characteristics of the membranes has been investigated. The scanning electron microscopy of the coated fabric reveals porous structure. The porosi...
