pH-Controllable drug release using hydrogel encapsulated mesoporous silica.
نویسندگان
چکیده
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 protein drug to the site of higher pH value, such as small intestine or colon.

Preparation and evaluation of a thermosensitive liposomal hydrogel for sustained delivery of danofloxacin using mesoporous silica nanoparticles
Background: Sustained release delivery system can reduce the dosage frequency and maintain the therapeutic level of drugs for a longer time. Biodegradable, biocompatible and thermosensitive chitosan-beta-glycerophosphate (C-GP) solutions can solidify at body temperature and maintain their physical integrity for a longer duration. OBJECTIVES: To develop a novel delivery system based on the integ...
متن کاملHollow Mesoporous Silica Nanoparticles (HMSNs) Synthesis and in vitro Evaluation of Cisplatin Delivery
Cisplatin continues to be a first line chemotherapy agent alone or in combination with other cytotoxic agents orradiotherapy. Dose-limiting side effects, intrinsic and acquired resistance are the main reasons for inventing and developing new ways of delivering cisplatin. Biocompatible hollow porous materials offer high void volume, shell porosity, low density and controllable size which make th...
متن کاملPreparation and Characterization of Rifampin Loaded Mesoporous Silica Nanoparticles as a Potential System for Pulmonary Drug Delivery
The goal of this research is to determine the feasibility of loading rifampin into mesoporous silica nanoparticles. Rifampin was selected as a model lipophilic molecule since it is a well-documented and much used anti tuberculosis drug. The mesoporous silica nanoparticles were prepared by using Tetraethyl ortho silicate and cetyltrimethyl ammonium bromide (as surfactant); The prepared nanoparti...

متن کاملMagnetic mesoporous silica nanoparticles for potential delivery of chemotherapeutic drugs and hyperthermia.
Magnetic mesoporous silica (MMS) nanoparticles with controllable magnetization have been synthesized by encapsulating Fe3O4 nanoparticles in a mesoporous silica matrix. The structure, magnetic heating capacity and drug delivery ability of MMS nanoparticles were evaluated. The results showed that MMS nanoparticles had an average particle size of 150 nm and showed low cytotoxicity and efficient c...
