Here, we report a pH-responsive drug-carrier based on chondroitin sulfate functionalized mesostructured silica nanoparticles (NMChS-MSNs) ie, the amidation between NMChS macromer and amino group functionalized MSNs. The prepared nanoparticles were characterized using dynamic light scattering, fourier transform infrared spectroscopy and transmission electron microscopy. The resultant NMChS-MSNs were uniform spherical nanoparticles with a mean diameter of approximately 74 nm. Due to the covalent graft of hydrophilic and pH responsive NMChS, the NMChS-MSNs could be well dispersed in aqueous solution, which is favorable to being utilized as drug carriers to construct a pH-responsive controlled drug delivery system. Doxorubicin hydrochloride (DOX), a well-known anticancer drug, could be effectively loaded into the channels of NMChS-MSNs through electrostatic interactions between drug and matrix. The drug release rate of DOX@NMChS-MSNs was pH dependent and increased with the decrease of pH. The in vitro cytotoxicity test indicated that NMChS-MSNs were highly biocompatible and suitable to use as drug carriers. Our results imply that chondroitin sulfate functionalized nanoparticles are promising platforms to construct the pH-responsive controlled drug delivery systems for cancer therapy.Keywords: mesoporous silica nanoparticle, pH sensitive, chondroitin sulfate, drug deliveryXi JQin JFan LDove Medical PressarticleMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol 2012, Iss default, Pp 5235-5247 (2012) |
