Fig. 2. The cellular uptake and cytotoxicity of ORMOSIL NPs. (A) The cellular location of ORMOSIL nanoparticle in A549 cells was imaged by TEM. (B) A549 cells were treated with ORMOSIL NPs at indicated concentrations of for 24 h, and cell viability was measured by CCK-8. (C) A549 cells were exposed to ORMOSIL NPs as indicated in (D), then the LDH activation was measured and normalized to control.
