TiONts-DTX cytotoxic activity evaluation.
Notes: PC-3 cells were treated with free DTX, activated DTX (DTX-PMPI), DTX grafted to TiONts (TiONts-DTX) or bare TiONts (concentration equivalent to TiONts-DTX) for 96 h. Each point corresponds to the mean values of five replicates ± SD (results shown are representative curves from two independent experiments).
Abbreviations: DTX, docetaxel; TiONts, titanate nanotubes; PMPI, p-maleimi-dophenyl isocyanate.
