Organo-modified mesoporous silica nanoparticles, loaded with ibuprofen into the pores and functionalized on the external surface with a stable Gd(iii)-DOTA-monoamide chelate, were prepared and explored as potential theranostic probes.

Functionalized silica nanotube (FSNT) possessing the phenanthroline moiety as a fluorescent receptor was fabricated by solgel reaction, and the binding ability of FSNT with metal ions was evaluated by fluorophotometry.

Abstract The goal of this study is to see how different chemically modified nanoparticles affect the performance and characteristics commercial cross-linked polyethylene (XLPE) as a polymeric insulator used in insulating power cables compare their properties order figure out what factors are most important improving XLPE properties. Silicon dioxide or silica, titanium dioxide, zinc oxide nanopa...

Cisplatin is used to treat a variety of tumors, but dose-limiting toxicities or intrinsic and acquired resistance limit its application in many types of cancer including breast. Cisplatin was attached to silica nanoparticles using aminopropyltriethoxy silane as a linker molecule and characterized in terms of size, shape, as well as the dissolution of cisplatin from the silica surface. The prima...

To study the importance of the surface charge for cellular uptake of silica nanoparticles (NPs), we synthesized five different single- or multifunctionalized fluorescent silica NPs (FFSNPs) by introducing various ratios of amino and sulfonate groups into their surface. The zeta potential values of these FFSNPs were customized from highly positive to highly negative, while other physicochemical ...

a series of fe3o4 supported on mesoporous fdu-12 silica systems were prepared by the hydrothermal conditions. the surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like ftir, xrd, n2 adsorption–desorption and tem. xrd and adsorption–desorption analysis shows that the mesostructure of fdu silica remains intact after fe3o4 modifications, wh...

Single 15-crown-5 functionalized Au nanoparticles (NPs) were synthesized with assistance of silica particles. The use of silica particles renders intrinsic advantages in that each step along the product formation can be monitored by, for example, a transmission electron microscope, and large surface-to-volume ratio of silica particles leads to a better yield of Au NP attachment than the glass s...
