Mesoporus silica nanoparticles (MSNs) with multimodal pore channels were fully characterized by TEM, nitrogen adsorption–desorption and DLS analyses. MSNs with average diameter of 200 nm with dual pore channel zones with pore diameters of 1.3-2.6 and 4 nm were tested for their use in drug delivery application. Important role of the multimodal pore systems present on MSNs on the quantitative release of model drug ibuprofen was investigated. The results obtained revealed that the release profile for ibuprofen clearly shows distinct zones which can be attributed to the respective porous channel zones present on the particles. The fluctuations in the concentration of ibuprofen during the prolonged release from MSNs were caused by the multimodal pore channel systems.

Abstract

Mesoporus silica nanoparticles (MSNs) with multimodal pore channels were fully characterized by TEM, nitrogen adsorption–desorption and DLS analyses. MSNs with average diameter of 200 nm with dual pore channel zones with pore diameters of 1.3-2.6 and 4 nm were tested for their use in drug delivery application. Important role of the multimodal pore systems present on MSNs on the quantitative release of model drug ibuprofen was investigated. The results obtained revealed that the release profile for ibuprofen clearly shows distinct zones which can be attributed to the respective porous channel zones present on the particles. The fluctuations in the concentration of ibuprofen during the prolonged release from MSNs were caused by the multimodal pore channel systems.
