Table 1.

Different degrees of supersaturation (DS), ionic concentrations, pDNA concentrations, pDNA-CaP binding efficiencies, yield of the solid phase, crystallinity of phases (HAp = hydroxyapatite; DCP = brushite), and initial and final pH values of the solutions from which CaP-pDNA nanoparticles were precipitated.
