Silica network improve the effect of fludarabine and paclitaxel on HCT8 cell line.

This paper reports the potential of silica network to sensitize tumor cells and stimulate antitumor toxicity of fludarabine (FLU) and paclitaxel (PAC) against HCT8 cells. SiO₂, SiO₂/FLU and SiO₂/PAC nanostructured materials were characterized by X-Ray Diffraction, Scanning Electron Microscopy, InfraRed Microscopy and in vitro biological assays. When using SiO₂/PAC, it can be observed that the cytostatic effect of PAC is boosted only at high concentrations of this material.
