Facile preparation of multifunctional Fe3O4@SiO2@LaVO4:Eu3+ nanocomposites as potential drug carriers

Construction of Lanthanum Vanadate/Functionalized Boron Nitride Nanocomposite: The Electrochemical Sensor for Monitoring of Furazolidone

“…Most importantly, the custom of tetrahedral oxyanions (VO 4 ) 3– as structural building blocks with RE metals (4f orbitals) is a good way to enrich the physiochemical activity. − The most stable valence state of RE is 3+, which highly imposes a 3+ valence state to the (VO 4 ) 3– in the electronic spin state. By virtue of the physicochemical characteristics, lanthanum vanadate (LaVO 4 ; LaV) is recognized to be an excellent and robust candidate among the (RE)­VO 4 family. − As a typical tetragonal zircon-type structure, LaV has much attention in the technological applications due to its moderate band gap, tunable catalytic properties, conductivity, and structural stability. − The electrochemical properties of LaV are inferred from the charge distribution between La 3+ and [VO 4 ] 3– units. Until now, the detailed crystal studies are entirely recognized, but the electrochemical applications of LaV have not yet been examined.…”

Silica-Coated Fe3O4Nanoparticles as a Bifunctional Agent for Magnetic Resonance Imaging and ZnII Fluorescent Sensing

“…Dual functional and multifunctional magnetic core shell Fe 3 O 4 @SiO 2 nanocomposites as a special carrier have attracted more and more attention. [1][2][3][4][5][6] The silica shell outside the iron oxide core not only increases the and biocompatibility and stability of nanoparticles in water environment, but also provides convenient sites for modifying ligands in biomedical applications, such as biological separation, [7][8][9] drug targeting, [10][11][12][13][14] cell separation, 8 enzyme immobilization [15][16][17][18] and protein purification. 19 In addition, Fe 3 O 4 @SiO 2 MNPs are more and more studied because they are easy to prepare and friendly to aqueous solution, 20 and can be designed into various shapes and sizes.…”
