To overcome these limitations, passive and active cell targeting drug delivery systems were explored. TDC was intercalated into layered zirconium phosphate nanoparticles (TDC@ZrP), passive carriers enabling acid-triggered release under lysosomal environments. Bovine serum albumin (BSA) binding and conjugation to receptor-targeted deferasirox-peptide ligands were used as active carriers. TDC@ZrP increased intracellular Ti(IV) uptake by ∼ 26-fold relative to free TDC, yet without an increase in antiproliferative activity. Similarly, stabilization with BSA enhanced solution stability but not cytotoxicity. In contrast, Ti(Def)<sub>2</sub> showed transporter-dependent activity. While albumin binding reduced its efficacy, conjugation to a transferrin receptor-1 targeting peptide significantly enhanced titanium uptake and cytotoxicity. Targeting the neurokinin-1 receptor had minimal effect, consistent with low receptor expression.
