Nanomaterials are structures whose exceptionality is based on their large surface, which is closely connected with reactivity and modification possibilities. Due to these properties nanomaterials are used in textile industry (antibacterial textiles with silver nanoparticles), electronics (high-resolution imaging, logical circuits on the molecular level) and medicine. Medicine represents one of ...
Magnetic resonance based molecular imaging has emerged as a very promising technique for early detection and treatment of a wide variety of diseases, including cancer, neurodegenerative disorders, and vascular diseases. The limited sensitivity and specificity of conventional MRI are being overcome by the development of a new generation of contrast agents, using nanotechnology approaches, with i...
PURPOSE This research was conducted to assess the biocompatibility of the core-shell Fe(3)O(4)@ Au composite magnetic nanoparticles (MNPs), which have potential application in tumor hyperthermia. METHODS Fe(3)O(4)@Au composite MNPs with core-shell structure were synthesized by reduction of Au(3+) in the presence of Fe(3)O(4)-MNPs prepared by improved co-precipitation. Cytotoxicity assay, hemo...
This work reports on the structural modification of cellulosic materials with magnetic iron oxide nanoparticles through co-precipitation method. Cellulose is one most abundant natural polymers chemical variability brought about by presence several hydroxyl groups, allowing its surface modifications insertion groups to impact characteristics. Thus, objective this study was synthesize (MNPs) co-p...
In the recent years, nanotechnology has attained much attention in the every field of science. The synthesis, characterisation and applications of metallic nanoparticles (MNPs) have become an important branch of nanotechnology. In the current study, MNPs were synthesised through polyols process and applied in vitro to study their effect on medicinally important plant : Artemisia absinthium. The...
Bi1-xBaxFeO3 (x = 0.02, 0.04 and 0.07) multiferroic materials with a diameter in the range of 30-40 nm were controllably synthesized by a facile ultrasonic method, with a very short reaction time of 5 min at a low temperature of 30 °C, and the resulting BiFeO3 magnetic nanoparticles (BFO MNPs) exhibited enhanced magnetic and photocatalytic performance. The substitution of Ba2+ ions for Bi3+ ion...
Abstract One of the main challenges in hyperthermia treatment is how to improve heating performance nanoparticles with high specific loss power (SLP). To tackle this challenge, magnetite (MNPs) and coated polyvinyl alcohol (PVA@MNPs) were fabricated via ultrasonic-assisted coprecipitation technique. The obtained characterized by using FT-IR, TEM, TGA, XRD, ICP-OES, DLS, zeta potential, VSM UV–V...
It has been demonstrated that the cellular defect in Tangier disease is associated with morphological abnormalities in the lysosomal compartment and in the Golgi apparatus of mononuclear phagocytes (MNPs) after lipid loading by exposure to acetylated low density lipoproteins (acetyl-LDLs). On exposure to acetyl-LDL, Tangier MNPs accumulate two unusual types of vacuoles that were not observed in...
It is of tremendous interest to use nanoparticles (NPs) as building blocks for the fabrication of multifunctional mesoscale assemblies by organizing them into twoand threedimensional structures with precise size and shape control for applications based on their collective properties. 2] Several ways have been reported to create ordered assemblies of NPs by using templates that have sites with s...
Abstract The influence of the plasmon three spherical metal nanoparticles (MNPs) on semiconductor quantum dot (SQD) having external fields is analyzed. density matrix equations are modified for description optical properties SQD-MNPs nanosystem. We study theoretically role plasmon–exciton dipole coupling in investigate dependence nanosystem position MNPs with respect to SQD as well material par...
