Nature materials, 12(4), 310-314 (2013-02-05)
The formation of crystalline materials from solution is usually described by the nucleation and growth theory, where atoms or molecules are assumed to assemble directly from solution. For numerous systems, the formation of the thermodynamically stable crystalline phase is additionally

Magnetotactic bacteria align along the Earth's magnetic field using an organelle called the magnetosome, a biomineralized magnetite (Fe(II)Fe(III)2O4) or greigite (Fe(II)Fe(III)2S4) crystal embedded in a lipid vesicle. Although the need for both iron(II) and iron(III) is clear, little is known
Maoquan Chu et al.
Biomaterials, 34(16), 4078-4088 (2013-03-08)
The photothermal effect of Fe3O4 magnetic nanoparticles is investigated for cancer therapy both in vitro and in vivo experiments. Heat is found to be rapidly generated by red and near-infrared (NIR) range laser irradiation of Fe3O4 nanoparticles with spherical, hexagonal and wire-like
A Aranda et al.
Toxicology in vitro : an international journal published in association with BIBRA, 27(2), 954-963 (2013-01-30)
No consensus exists on how to address possible toxicity of nanomaterials as they interfere with most in vitro screening tests based on colorimetric and fluorimetric probes such as the dichloro-dihydro-fluorescein diacetate (DCFH-DA) assay for detection of oxidative species. In the
Tsung-Ju Li et al.
Biomaterials, 34(32), 7873-7883 (2013-07-24)
We present an approach for synchronizing hyperthermia and thermal-responsive local drug release. The targeting probe has a magnetite nanocrystal (Fe₃O₄@PSMA) core and a polynucleotide shell that carries 5-fluorouracil (5-FU) and anti-human epidermal growth factor receptor 2 (anti-HER2) antibody for cancer

Graphene-Based Composites and their Unique Renewable Energy Applications

Graphene is a unique two-dimensional (2D) structure of monolayer carbon atoms packed into a dense honeycomb crystal that has attracted great interest due to its diverse and fascinating properties.

Strategy for Toxicity Screening of Nanomaterials

A key challenge for nanomaterial safety assessment is the ability to handle the large number of newly engineered nanomaterials (ENMs), including developing cost-effective methods that can be used for hazard screening.

Recent Developments in Magnetic Iron Oxide Nanoparticles for Non-Invasive Bioimaging

Professor Hui Mao explores the use of superparamagnetic iron oxide nanoparticles (INOPs) that offer an alternate contrast-enhancing mechanism.

Synthesis and Application of Shape-Controlled Fe3O4 Nanostructure

Professor Yadong Yin (University of California Riverside, USA) examines both direct (thermal decomposition, solvothermal, hydrothermal) and indirect (templated) synthesis methods of magnetite nanocrystals and reviews in detail the landscape of these various synthetic methods for magnetite nanocrystal and their applications in magnetic assembly, magnetic hyperthermia, and Li-Ion batteries.
