We report here a nanoparticle design featuring pH-responsive alkoxyphenyl acylsulfonamide ligands. Due to ligand structure, this nanoparticle is neutral at pH 7.4, becoming positively charged at tumor pH (< 6.5). The particle uptake and cytotoxicity increases over this pH range. This pH-controlled uptake and toxicity makes this particle a promising tool for cancer therapeutics.
