Hydrophobic Magnetite Nanoparticles for Bioseparation: Green Synthesis, Functionalization, and Characterization

Facile Surface Functionalization of Hydrophobic Magnetic Nanoparticles

Nonpolar phase synthesized hydrophobic nanocrystals show attractive properties and have demonstrated prominent potential in biomedical applications. However, the preparation of biocompatible nanocrystals is made difficult by the presence of hydrophobic surfactant stabilizer on their surfaces. To address this limitation, we have developed a facile, high efficiency, single-phase and low-cost meth...

Synthesis, Characterization, and SERS Functionalization of Hollow Gold Nanoparticles

Hollow gold nanoparticles formed by galvanic replacement reactions have been extensively studied because their increased surface area and tunable optical properties have applications in catalysis, drug delivery, and photothermal cancer therapies. In this study, hollow gold nanoparticles (size 30-40 nm) were synthesized by transmetallation of tyrosinereduced sacrificial solid silver nanospheres....

A Comparison between Chemical Synthesis Magnetite Nanoparticles and Biosynthesis Magnetite

The preparation of Fe3O4 from ferrous salt by air in alkaline aqueous solution at various temperatures was proposed. The synthetic magnetites have different particle size distributions. We studied the properties of the magnetite prepared by chemical methods compared with magnetotactic bacterial nanoparticles. The results show that crystallite size, morphology, and particle size distribution of ...

Functionalization of Magnetite Nanoparticles as Oil Spill Collector

In the present study, a new magnetic powder based on magnetite can be used as a petroleum crude oil collector. Amidoximes based on rosin as a natural product can be prepared from a reaction between hydroxylamine and rosin/acrylonitrile adducts. The produced rosin amidoximes were used as capping agents for magnetite nanoparticles to prepare hydrophobic coated magnetic powders. A new class of mon...
