Physiological Remediation of Cobalt Ferrite Nanoparticles by Ferritin
Metallic nanoparticles have been increasingly suggested as prospective therapeutic nanoplatforms, yet their long-term fate and cellular processing in the body is poorly understood. Here we examined the role of an endogenous iron storage protein - namely the ferritin - in the remediation of biodegradable cobalt ferrite magnetic nanoparticles. Structural and elemental analysis of ferritins close ...
متن کاملHigh-Performance Ferrite Nanoparticles through Nonaqueous Redox Phase Tuning.
From magnetic resonance imaging to cancer hyperthermia and wireless control of cell signaling, ferrite nanoparticles produced by thermal decomposition methods are ubiquitous across biomedical applications. While well-established synthetic protocols allow for precise control over the size and shape of the magnetic nanoparticles, structural defects within seemingly single-crystalline materials co...
متن کاملR-Ferrite-type barium cobalt stannate, BaCo2Sn4O11
BaCo(2)Sn(4)O(11) is isotypic with R-ferrite, BaTi(2)Fe(4)O(11). The Co atoms fully occupy trigonal-bipyramidal sites () and are disordered with Sn atoms in octa-hedral sites (.2/m symmetry), as represented in the formula BaCoSn(2)(Co(0.34)Sn(0.66))(4)O(11). Ba atoms are situated in a 12-fold coordinated site ( symmetry).
متن کاملAtomically flat ultrathin cobalt ferrite islands.
A route for fabricating structurally perfect cobalt ferrite magnetic nanostructures is demonstrated. Ultrathin islands of up to 100 μm(2) with atomically flat surfaces and free from antiphase boundaries are developed. The extremely low defect concentration leads to a robust magnetic order, even for thicknesses below 1 nm, and exceptionally large magnetic domains. This approach allows the evalua...
متن کاملCobalt ferrite nanocrystals: out-performing magnetotactic bacteria.
Magnetotactic bacteria produce exquisitely ordered chains of uniform magnetite (Fe(3)O(4)) nanocrystals, and the use of the bacterial mms6 protein allows for the shape-selective synthesis of Fe(3)O(4) nanocrystals. Cobalt ferrite (CoFe(2)O(4)) nanoparticles, on the other hand, are not known to occur in living organisms. Here we report on the use of the recombinant mms6 protein in a templated sy...
