- critical importance of interfaces. In the current issue, from “simple” to more elaborated, we here observe the importance of the polyol method, the non-hydrolytic or colloidal approach, and ordered mesopore templating techniques. In “Tailoring the magnetic properties of cobalt ferrite nanoparticles using
Tailoring the magnetic properties of cobalt ferrite nanoparticles using the polyol process
Beilstein J. Nanotechnol. 2019, 10, 1166–1176, doi:10.3762/bjnano.10.116
- temperature and precursor concentration are determining the final products in composition, shape, and size. Cobalt ferrite nanoparticles (NPs) have already been produced by the polyol process in one or in several steps. However, little research has focused on the relationship between the NP size and the
Methionine-mediated synthesis of magnetic nanoparticles and functionalization with gold quantum dots for theranostic applications
Beilstein J. Nanotechnol. 2017, 8, 1734–1741, doi:10.3762/bjnano.8.174
- methionine-functionalized cobalt ferrite nanoparticles A hydrothermal approach was applied to synthesize the superparamagnetic cobalt ferrite NPs stabilized with methionine. The proposed approach differs from the reported one [19] in the nature of magnetic NPs, the composition of the aqueous solution applied
- −1 due to cooperative vibrations of –CH3 and –NH2 groups is indicative of the oxidation of methionine to methionine sulfoxide. However, this mechanism requires more specific evidence and needs to be studied. Conclusion Superparamagnetic methionine-coated cobalt ferrite nanoparticles with an average

Synthesis of Co-ferrite nanoparticles: Superparamagnetic cobalt ferrite nanoparticles were synthesized by a hydrothermal approach in an alkaline solution (40 mL) of Co(II) and Fe(III) chlorides, at a molar
Hemolysin coregulated protein 1 as a molecular gluing unit for the assembly of nanoparticle hybrid structures
Beilstein J. Nanotechnol. 2016, 7, 351–363, doi:10.3762/bjnano.7.32
- gluing unit for the assembly of often linear, hybrid structures of plasmonic gold (Au NP), magnetite (Fe3O4 NP), and cobalt ferrite nanoparticles (CoFe2O4 NP). Furthermore, the assembly of Au NPs into linear structures using Hcp1_cys3 is investigated by UV–vis spectroscopy, TEM and cryo-TEM. One key
Predicting cytotoxicity of PAMAM dendrimers using molecular descriptors
Beilstein J. Nanotechnol. 2015, 6, 1886–1896, doi:10.3762/bjnano.6.192
- techniques in this field. For instance, Liu et al. analyzed a number of attributes of a variety of nanoparticles in order to predict the 24 hour postfertilization mortality in zebrafish [3]. Horev-Azaria and colleagues used predictive modeling to explore the effect of cobalt–ferrite nanoparticles on the
Manipulation of isolated brain nerve terminals by an external magnetic field using D-mannose-coated γ-Fe2O3 nano-sized particles and assessment of their effects on glutamate transport
Beilstein J. Nanotechnol. 2014, 5, 778–788, doi:10.3762/bjnano.5.90
- have a potential to cross the blood brain barrier that may open new ways for drug delivery into the brain [22]. Cobalt ferrite nanoparticles coated by silica, with a size of 50 nm, were found in the brain after being administered via an intravenous injection in mice [23]. After exposure of mice to TiO2
Oriented attachment explains cobalt ferrite nanoparticle growth in bioinspired syntheses
Beilstein J. Nanotechnol. 2014, 5, 210–218, doi:10.3762/bjnano.5.23
- cobalt ferrite nanoparticles in a bioinspired synthesis was studied. Bioinspired syntheses have sparked great interest in recent years due to their ability to influence and alter inorganic crystal growth and therefore tailor properties of nanoparticles. In this synthesis, a short synthetic version of the

- . In this work, the underlying non-classical growth process of the biosynthesized cobalt ferrite nanoparticles, discussed in our previous work, was investigated [20]. Biomimetic approaches aim to specifically tailor particle properties under mild conditions, which cannot be achieved with conventional
Review and outlook: from single nanoparticles to self-assembled monolayers and granular GMR sensors
Beilstein J. Nanotechnol. 2010, 1, 75–93, doi:10.3762/bjnano.1.10
- the C-terminal region of Mms6. In this study, cobalt ferrite nanoparticles not known to occur in magnetotactic bacteria were synthesized. Cobalt and iron salts were added to the c25-mms6 mixture and incubated at 4 °C. The mixture was stirred under argon flux until it reached room temperature and then
