pH-Controllable drug release using hydrogel encapsulated mesoporous silica.
Amine-functionalized mesoporous SBA-15 silica loaded with bovine serum albumin (BSA) has been successfully encapsulated with a thin layer coating of poly(acrylic acid) PAA, with the entrapped BSA being released from the PAA-encapsulated SBA-15 at the higher pH value of 7.4 rather than at the lower pH value of 1.2. This novel drug delivery system has a potential application in the release of pro...
متن کاملPhase-Selective Catalysis in Emulsions Stabilized by Janus Silica- Nanoparticles
Metal-containing Janus particles are used as interfacial catalyst/emulsifiers that catalyze reactions in biphasic systems with controlled “phase selectivity”, that is, conversion of the desired reaction on one side of the emulsion. The reaction may affect the solubility of the molecule in one phase, causing migration to the opposite phase. As a result, combined reaction and separation can be ac...
متن کاملPd(II) immobilized on mesoporous silica by N-heterocyclic carbene ionic liquids and catalysis for hydrogenation.
In this work we synthesized Pd(II) immobilized on mesoporous silica by N-heterocyclic carbene (NHC) ionic liquids (ILs) with different alkyl chain lengths. The catalysts were characterized by Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), low-angle X-ray powder diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), ...
متن کاملPreparation of bifunctional mesoporous silica nanoparticles by orthogonal click reactions and their application in cooperative catalysis.
The synthesis of bifunctional mesoporous silica nanoparticles is described. Two chemically orthogonal functionalities are incorporated into mesoporous silica by co-condensation of tetraethoxysilane with two orthogonally functionalized triethoxyalkylsilanes. Post-functionalization is achieved by orthogonal surface chemistry. A thiol-ene reaction, Cu-catalyzed 1,3-dipolar alkyne/azide cycloadditi...
متن کاملDetermination of the Effect of Sono-Photo Dynamic Therapy by using dual frequency in the presence of Mesoporous Silica Nanoparticles Encapsulated Porphyrin in the Treatment of Adenocarcinoma
Introduction: Breast cancer is the most common cancer among women in the world and in Iran. Sono- photodynamic therapy is a new modality for cancer treatment. In this method, a sensitizer that activates by ultrasound and light produces photochemical and synchochemical activities, thereby causing the toxicity and destruction of tumor cells. The use of dual frequency ultrasound...
