Synthesis and in vitro testing of thermoresponsive polymer-grafted core-shell magnetic mesoporous silica nanoparticles for efficient controlled and targeted drug delivery
(Academic Press Inc Elsevier Science, 2019-05)
In this work, thermoresponsive polymer grafted magnetic mesoporous silica nanoparticles were prepared, fully characterized and tested as controlled drug delivery systems. For this purpose, iron oxide nanoparticles coated ...
In Vivo Tracking of the Degradation of Mesoporous Silica through 89Zr Radio-Labeled Core–Shell Nanoparticles
(Wiley VCH Verlag, 2021-06)
While mesoporous silica nanoparticles (MSNs) are extensively studied as high-potential drug delivery platforms, the successful clinical translation of these nanocarriers strongly depends on their biodistribution, biodegradation, ...
Following in situ the degradation of mesoporous silica in biorelevant conditions: At last, a good comprehension of the structure influence
(American Chemical Society, 2020-02-20)
Mesoporous silica nanoparticles (MSNs) have seen a fast development as drug delivery carriers thanks to their tunable porosity and high loading capacity. The employ of MSNs in biomedical applications requires a good ...
Preparation and study of the antibacterial applications and oxidative stress induction of copper maleamate-functionalized mesoporous silica nanoparticles
(MDPI AG, 2019-01)
Mesoporous silica nanoparticles (MSNs) are an interesting class of nanomaterials with potential applications in different therapeutic areas and that have been extensively used as drug carriers in different fields of medicine. ...
Adsorption of reactive dyes on titania-silica mesoporous materials
(Academic Press Inc Elsevier Science, 2006-07)
This paper presents a study on the adsorption of two basic dyes, methylene blue (MB) and rhodamine B (RhB), from aqueous solution onto mesoporous silica-titania materials. The effect of dye structure, adsorbent particle ...
Sodium Hexametaphosphate: An Inexpensive Inorganic Polyelectrolyte “Primer” For Upconverting Nanoparticles/Mesoporous Silica Core-Shell Synthesis
(Wiley-VCH, 2020-05)
We introduce a method for depositing a uniform mesoporous SiO2 layer onto upconverting nanoparticles (UCNPs) following a two step approach. First, thermolysis synthesized hydrophobic oleate-capped UCNP were subjected to a ...
A new synthesis pathway for colloidal silica spheres coated with crystalline titanium oxide and its comparative cyto- and genotoxic study with titanium oxide nanoparticles in rat osteosarcoma (UMR106) cells
(Elsevier Science, 2013-03)
Spherical particles with an amorphous core of silica and a crystalline shell of titanium oxide (SiO2@TiO2) formed in a three-step procedure, being the last step a mild chemical treatment. SiO2@TiO2 had a shell with pores ...
Synthesis and characterization of nanoparticulate silica with organized multimodal porous structure impregnated with 12-phosphotungstic acid for its use in heterogeneous catalysis
(Elsevier Science, 2018-10-16)
Mesoporous silica (MESSI) nanoparticles with ordered mesoporous frameworks were successfully obtained using the triblock copolymer P123 as the mesoporous template and agar as micropore former. The agar/TEOS ratio influences ...
Electrochemical biointerfaces based on carbon nanotubes-mesoporous silica hybrid material: Bioelectrocatalysis of hemoglobin and biosensing applications
(Elsevier Advanced Technology, 2018-07)
We are reporting a novel biosensing platform based on a hybrid nanomaterial that combines the advantages of Nafion-coated multiwalled carbon nanotubes (MWCNTs) and mesoporous silica MCM41 nanoparticles functionalized with ...
Structural and Mechanical Properties of Silica Mesoporous Films Synthesized Using Deep X-Rays: Implications in the Construction of Devices
(Frontiers Media, 2021-02-19)
In recent years, the use of X-Rays (XR) irradiation for the production of ordered mesoporous thin films has been well established. This technique allows obtaining porous materials that contain thermal sensitive moieties ...
