Preparation of pH-Responsive Mesoporous Silica Nanoparticles and Their Application in Controlled Drug Delivery
Abstract
Poly(acrylic acid) grafted mesoporous silica nanoparticles (PAA-MSNs) were prepared by a facile graft-onto strategy, i.e., the amidation between PAA homopolymer and amino group functionalized MSNs. The resultant PAA-MSNs were uniform spherical nanoparticles with a mean diameter of approximately 150 nm, and the graft amount of PAA evaluated by thermogravimetric analysis (TGA) was about 12 wt %. Due to the covalent graft of hydrophilic and pH-responsive PAA, the PAA-MSNs could be well dispersed in aqueous solution, which is favorable to be utilized as drug carriers to construct a pH-responsive controlled drug delivery system. N 2 adsorption–desorption isotherm results demonstrated that doxorubicin hydrochloride (DOX), a well-known anticancer drug, could be effectively loaded into the channels of PAA-MSNs through the electrostatic interaction. The loading content and the entrapment efficiency of DOX could reach up to 48% and 95%, respectively. The drug release rate of DOX@PAA-MSN was pH dependent and increased with the decrease of pH. The in vitro cytotoxicity test indicated that PAA-MSNs were highly biocompatible and suitable to use as drug carriers. The drug-loaded DOX@PAA-MSNs were distinctly cytotoxic to HeLa cells, due to the sustained release of drug, and showed higher clinical effects than free DOX. These results imply that the PAA-MSNs are promising platforms to construct pH-responsive controlled drug delivery systems for cancer therapy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
