Abstract

For treating bone cancer, controlled drug delivery is an important strategy. Bioactive scaffolds are widely used biomaterials due to their usefulness in localized drug delivery. The aim of this study was to develop mesoporous bioglass (MBG) with improved bioactivity and controllable drug delivery rate. By using pluronic 123 (P123) as a template, a facile sol-gel route was employed for the synthesis of MBG nanoparticles (NPs). The composition of the prepared sample was estimated by using energy dispersive X-ray spectroscopy (EDX). These nanoparticles demonstrated the specific surface area of 310m2/g and pore size of 13nm as measured by brunauer-emmett-teller (BET) and barrett-joyner-halenda (BJH) method, respectively. The spherical shape of NPs was confirmed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Imatinib (IMT); an anti-cancer drug was loaded with the efficiency of 77.59%. The drug release kinetics were precisely controlled by changing the pH (4.4 to 10.4) as well as drug loading concentration (0.2-1.0mg/mL). The maximum cumulative drug release of 81% was observed over a time period of 250h at pH of 4.4. Importantly, significant inhibitory effects on the viability of the MG-63 osteocarc...Continue Reading
