Magnetic pH-sensitive microcontainers were produced by a four-step process. The first step involves the synthesis of citrate-modified magnetic nanoparticles via the coprecipitation method. The second step consists of the encapsulation of magnetic nanoparticles in non-cross-linked poly(methacrylic acid) (PMAA) microspheres through distillation precipitation polymerization, resulting in a core/sh...
A biocompatible, multimodal, and theranostic functional iron oxide nanoparticle is synthesized using a novel water-based method and exerts excellent properties for targeted cancer therapy, and optical and magnetic resonance imaging. For the first time, a facile, modified solvent diffusion method is used for the co-encapsulation of both an anticancer drug and near-infrared dyes. The resulting fo...
bis-(l-tyrosinato)copper(ii) was reacted with 3-(chloropropyl)-trimethoxysilane functionalized silica that has infused magnetite to yield a magnetically separable catalyst in which the copper carboxylate is covalently linked to the silica matrix through the silane linkage. the immobilized catalyst has been characterized by spectroscopic studies (such as ft-ir, epr, magnetic measurement, sem) an...
we expressed and purified a recombinant p. pyralis luciferase with n-terminal his-tags. the silanized ni or cu-loaded magnetic particles were prepared and used to assemble the his-tagged p. pyralis luciferase. this enzyme immobilized on functionalized magnetic nanoparticles (mnps) via electrostatic interactions of his-tag with ni2+/cu2+ ions on the surface of mnps using simple one step method. ...
recent advances in nanotechnology have rapidly developed new therapeutic and diagnostic concepts in all aspects of medicine. magnetic nanoparticles (mnps) can be simultaneously functionalized and guided by a magnetic field, thus providing promising tools for several biomedical applications. mnps contrast agents at low concentrations offer the potential to significantly improve existing methods o...
background: nowadays, magnetic nanoparticles (mnps) have received much attention because of their enormous potentials in many fields such as magnetic fluid hyperthermia (mfh). the goal of hyperthermia is to increase the temperature of malignant cells to destroy them without any lethal effect on normal tissues. to investigate the effectiveness of cancer therapy by magnetic fluid hyperthermia, fe...
