Background: Protein purification is the most complicated issue in the downstream processes of recombinant protein production; therefore, improved selective purification methods are important. Affinity-based protein purification method using His-tag and Ni-NTA resins is one of the most common strategies. MNPs can be used as a beneficial alternative for Ni-NTA resins. However, there is no data on...
Fe3O4 magnetic nanoparticles (MNPs) have been widely used as a recyclable catalyst in Fenton reaction for organic degradation. However, the pristine MNPs suffer from drawbacks of iron leaching acidic conditions well decreasing catalytic activity degradation at pH higher than 3.0. To solve problems, were modified by poly(catechol) (Fe3O4/PCC MNPs) using facile chemical co-precipitation method. T...
Superparamagnetic magnetite nanoparticles (MNPs), Fe3O4, were synthesized via the modified coprecipitation method. The morphology of these MNPs is polyhedral. The particle size of MNPs ranged from 20 to 100 nm. For combined hyperthermia and thermoresponsive drug delivery applications, the heating element, MNPs, in the core of drug carriers should increase the temperature of the target up to 43 ...
Abstract Aflatoxin B1 (AFB1) is a highly toxic mycotoxin that enters the human body through food chain and poses serious threat to health. In this paper, polydopamine (PDA)-coated Fe3O4 magnetic nanoparticles (Fe3O4@PDA MNPs) were prepared by co-precipitation method enrich aflatoxin from edible oil. Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy, X-ray photoelec...
We report a high-performance chemiresistive sensor for detection of volatile organic compound (VOC) vapors based on core-shell hybridized nanostructures of Fe3O4 magnetic nanoparticles (MNPs) and poly(3,4-ethylenedioxythiophene) (PEDOT)-conducting polymers. The MNPs were prepared using microwave-assisted synthesis in the presence of polymerized ionic liquids (PILs), which were used as a linker ...
one-pot reaction of aldehydes or ketons with aniline derivatives was performed using nabh4 and fe3o4 magnetic nanoparticles (mnps). the optimum amount of fe3o4 mnps was 5 mol% under solvent free condition. the corresponding products were obtained in good to excellent yields. the magnetically recoverable iron oxide nanoparticles are found to be efficient for synthesis of amine derivatives. these...
BACKGROUND Traditional Chinese medicine wogonin plays an important role in the treatment of leukemia. Recently, the application of drug-coated magnetic nanoparticles (MNPs) to increase water solubility of the drug and to enhance its chemotherapeutic efficiency has attracted much attention. Drugs coated with MNPs are becoming a promising way for better leukemia treatment. This study aimed to ass...
In this study, we developed a platform that can be used to rapidly enrich polyhistidine(His)-tagged proteins/peptides from complex samples selectively using the Fe3O4@Al2O3 magnetic nanoparticles (MNPs) as the affinity probes. At pH 7, the dissociation constant between poly-His, i.e., His6, and the Fe3O4@Al2O3 MNPs was ~10(-5) M and the trapping capacity was ~100 nmol/mg for His6. Enrichment wa...
Different phosphates and phosphonates have shown excellent coating ability toward magnetic nanoparticles, improving their stability biocompatibility which enables biomedical application. The hyperthermia efficiency of (IDP IHP) (MDP HEDP) coated Fe3O4 nanoparticles (MNPs) were evaluated in an alternating field. For a deeper understanding hyperthermia, the behavior investigated MNPs non-alternat...
Introduction: Magnetic nanoparticle (MNP) hyperthermia is a promising cancer treatment approach. It is based on the evidence that by injecting MNPs such as Fe3O4 in the tumor and subjecting them to an alternating magnetic field, they release heat, generating temperatures up to 42°C that can kill cancer cells by apoptosis, usually with lowest damage to normal tissue. In previous...
