DLS Number Mean Diameter and Polydispersity Index (PDI) for TiO₂ and Tf/TiO₂ Nanoparticles Synthesized with Varying Concentrations of Tf^a

material	number mean diameter (nm)	zeta potential (mV)	PDI
bare TiO₂	25.38	45.1 ± 10.8	0.38
Tf:TiO₂ 1:3	37.74	35 ± 12.4	0.293
Tf:TiO₂ 1:1	47.39	37.5 ± 9.68	0.331
Tf:TiO₂ 2:1	58.54	37.4 ± 9.2	0.394

All measurements were taken at pH 4.
