Prussian blue-type nanoparticles and nanocomposites : synthesis, devices, and applications by Joulia Larionova( )

8 editions published in 2019 in English and Undetermined and held by 105 WorldCat member libraries worldwide

Nanochemistry tools aid the design of Prussian blue and its analogue nanoparticles and nanocomposites. The use of such nanomaterials is now widely regarded as an alternative to other inorganic nanomaterials in a variety of scientific applications. This book, after addressing Prussian blue and its analogues in a historical context and their numerous applications over time, compiles and details the latest cutting-edge scientific research on these nanomaterials. It compiles and deatils the latest cutting-edge scientific research on these nanomaterials. The book provides an overview of the methodological concepts of the nanoscale synthesis of Prussian blue and its analogues, as well as the study and understanding of their properties and of the extent and diversity of application fields in relation to the major societal challenges of the 21st century on energy, environment, and health

Biocompatibility assessment of functionalized magnetic mesoporous silica nanoparticles in human HepaRG cells( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: Magnetic mesoporous silica nanoparticles (M-MSNs) are a promising class of nanoparticles for drug delivery. However, a deep understanding of the toxicological mechanisms of action of these nanocarriers is essential, especially in the liver. The potential toxicity on HepaRG cells of pristine, pegylated (PEG), and lipid (DMPC) M-MSNs were compared. Based on MTT assay and real-time cell impedance, none of these NPs presented an extensive toxicity on hepatic cells. However, we observed by transmission electron microscopy (TEM) that the DMPC and pristine M-MSNs were greatly internalized. In comparison, PEG M-MSNs showed a slower cellular uptake. Whole gene expression profiling revealed the M-MSNs molecular modes of action in a time- and dose-dependent manner. The lowest dose tested (1.6 æg/cm 2) induced no molecular effect and was defined as 'No Observed Transcriptional Effect level.' The dose 16 æg/cm 2 revealed nascent but transient effects. At the highest dose (80 æg/cm 2), adverse effects have clearly arisen and increased over time. The limit of biocompatibility for HepaRG cells could be set at 16 æg/cm 2 for these NPs. Thanks to a comparative pathway-driven analysis, we highlighted the sequence of events that leads to the disruption of hepatobiliary system, elicited by the three types of M-MSNs, at the highest dose. The Adverse Outcome Pathway of hepatic cholestasis was implicated. Toxicogenomics applied to cell cultures is an effective tool to characterize and compare the modes of action of many substances. We propose this strategy as an asset for upstream selection of the safest nanocarriers in the framework of regulation for nanobiosafety
Nanoparticules en environnement cellulaire : Impact de la nano-architecture sur l'internalisation, la biodégradation et les fonctionnalités thérapeutiques. by Anouchka Plan( )

1 edition published in 2019 in French and held by 1 WorldCat member library worldwide

Les nanoparticules inorganiques représentent des solutions innovantes dans le domaine médical aussi bien dans le diagnostic que la thérapie.La première partie de cette thèse aborde les interactions entre les nanoparticules magnétiques et les cellules souches. Nous avons cherché à mieux comprendre les paramètres influençant l'internalisation et la biodégradation et mis en évidence un impact de la fonctionnalisation, des protéines présentes dans le milieu de culture et de l'agrégation. L'impact des nanoparticules sur la différenciation des cellules souches a permis de mettre en évidence un processus de remagnétisation de nanoparticules dégradées pour certaines voies de différenciation.Dans la seconde partie, nous nous sommes intéressés à des thérapies anti-cancéreuses par hyperthermie et plus précisément l'impact du confinement intracellulaire. Ainsi nous avons montré que le confinement intracellulaire peut inhiber complètement le chauffage généré par hyperthermie magnétique mais qu'il peut au contraire faciliter la photothermie à des longueurs d'onde biologiquement compatibles. Enfin, la combinaison de la photothermie et d'une molécule anti-cancéreuse a permis d'obtenir une thérapie plus efficace avec moins d'effets secondaires
Synthesis, structure and magnetic properties of tris(pyrazolyl)methane lanthanide complexes: effect of the anion on the slow relaxation of magnetization1( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Abstract : Synthesis and magnetic properties of tris(pyrazolyl)methane lanthanide complexes. Abstract : We report on the synthesis, structure and investigation of magnetic properties of a series of six heteroleptic complexes of the general formula [Ln(Tpm)X3 ]· y MeCN (Tpm = tris(3, 5-dimethylpyrazolyl)methane; Ln = Tb, Dy, Er; X − = NO3 −, Cl − and y = 1 or 2). We demonstrate that the observation of a field-induced slow relaxation of magnetization is highly dependent on the anion's nature. While nitrate moieties appear to be suitable to stabilize the oblate electronic density of Dy 3+, chloride ions generate an equatorial crystal-field allowing the slow relaxation of the prolate Er 3+ ions
