Sentence examples for shell of silica from inspiring English sources
They propose sealing the nanoparticles within a thin shell of silica to minimise any toxic effects.
It revealed the successful sol-gel reaction of the shell of silica (SiO2) (25 30 nm) for encapsulation of the core of FePt nanoparticles.
However, in most of these mentioned approaches, the synthesis process of the core-shell nanoparticles involves a multistep high-temperature preparation and less biocompatibility, such as first preparation of core (seed spherical nanoparticles) and then coating a shell of silica on the surface of the nanoparticles.
The outer shell of silica not only protects the inner magnetite core from aggregation [16, 17] but also provides sites for flexible surface modification such as poly ethylene glycol) to render NP biocompatibility by preventing the nonspecific adsorption of proteins [18] and various targeting biomolecules [19, 20] to improve the targeting efficiency.
Nanoparticles are coated with a shell of silica to avoid potential toxic effects.
A similar template-based mode of inheritance of altered structures was demonstrated by Jennings [ 36] in the amoeba Difflugia corona, which builds a hard shell of silica particles with a single opening from which pseudopods extend.
The core was composed of superparamagnetic Fe3O4 nanoparticles, while the shell consisted of silica molecular sieve MCM-41 and was functionalized by rhodamine derived probe.
Electrophoretic separations were also conducted on CdSe/ZnS NCs encapsulated in a thin shell of functionalized silica.
As diatoms have shells made of silica they are protected from copepods and so are more likely to die without being eaten and thus take take their carbon to the ocean floor.
The core-shell structure of silica nanoparticles allows fluorescent dyes such as FITC to be trapped inside [34, 35].
The SA-FSNPs display stronger fluorescent signals than the FITC-labeled aptamer probably due to the special core-shell structure of silica nanoparticles which allow the fluorescent dyes entrapped inside to prevent them from photodamaging oxidation [38 42].
