Elucidation of the chemical logic of life is one of the grand challenges in biology, and essential to the progress of the upcoming field of synthetic biology. Treatment of microbial cells explicitly as a "chemical" species in controlled reaction (growth) environments has allowed fascinating discoveries of elemental formulae of a few species that have guided the modern views on compositions of a...
Magnetic Fluid Hyperthermia mediated by iron oxide nanoparticles is one of the most promising therapies for cancer treatment. Among different candidates, magnetite and maghemite have revealed to be some candidates due both their performance biocompatibility. Nonetheless, up date, literature comparing heating efficiency similar size scarce. To fill this gap, here we provide a comparison between ...
Magnetic nanoparticles (MNPs) are capable of generate heating power under the influence of alternating magnetic fields (AMF); this behaviour recently opened new scenarios for advanced biomedical applications, mainly as new promising tumor therapies. In this paper we have tested magnetic nanoparticles called magnetosomes (MNs): a class of MNPs naturally produced by magnetotactic bacteria. We ext...
Magnetotactic bacteria synthesize intracellular membrane-enveloped magnetite bodies known as magnetosomes which have been applied in biotechnology and medicine. A series of proteins involved in ferric ion transport and redox required for magnetite formation have been identified but the knowledge of magnetosome biomineralization remains very limited. Here, we identify a novel OxyR homolog (named...
Superparamagnetic iron oxide nanoparticles with appropriate surface modification can be widely used in various applications including magnetic resonance imaging (MRI) diagnostic contrast agents, anticancer therapy using hyperthermia, magnetic drug targeting, protein and enzyme immobilization, cell labeling and separation or RNA and DNA purification. All these biochemical and biomedical applicat...
Background: Magnetotactic bacteria are a heterogeneous group of Gram-negative prokaryote cells that produce linear chains of magnetic particles called magnetosomes, intracellular organelles composed of magnetic iron particles. Many important applications have been defined for magnetic nanoparticles in biotechnology, such as cell separation applications and acting as carriers of enzymes, antib...
