Synthesis and characterisation of biologically compatible TiO2 nanoparticles

Table 1 Exchange of the TiO₂-bound stearic acid chains with various carboxylic acids

^aDetermined by ¹H NMR (400 MHz, CDCl₃). ^bXRD powder pattern indicated essentially pure nanoparticles. ^cThe nanoparticles were not dispersible in any solvent. ^dBased on the recovery yield of ligand in acetonitrile. ^eDetermined by ¹H NMR (400 MHz, D₂O) after removal of the Boc group using HCl/dioxane (ammonium hydrochloride salt is obtained). ^fDetermined by ¹H NMR (400 MHz, D₂O)
