Synthesis of silver modified hydroxyapatite nanoparticle and evaluation of its biological properties <i>in vitro</i> for potential biomedical application

“…Generally, the surface with more high negative charge is favorable for adsorption of extracellular matrix and Ca 2+ ions, which can promote adhesion of bone cells and enhance the bioactivity of nanoparticles. 55) And the larger the absolute zeta potential, the stronger the electrostatic repulsion, the weaker the agglomeration tendency. 56)…”

Tuning Coordination Modes and Nucleation of Calcium Phosphate with Oligomeric Lactic Acid and pH Values: Theoretical and Experimental Study

“…Although the zeta potential values measured by different research groups may be different from each other, the experimental data of various nanoparticles collected in Table 1 could still give some general trends, especially for the potential of binding with the biological moelcules. As shown in Table 1, the HA nanoparticles with different morphologies, 14 Ag@HA, 30 F-Cl@HA, 31 and Au/Ag@ HA, 35 had negative zeta potentials, some of which were found to be efficiently taken up by A375 cells and MG-63 cells. The HA particles with several kinds of oxygencontaining addtives, such as, citric acid@HA, 32 oxalic acid@HA 33 and malic acid@HA 34 also exhibited negative zeta potentials, whose values were dependent on the pH values (Table 1), Similar to HA nanoparticles, some other nanoparticles including Au/Ag nanoparticles, 35 cerium oxide nanoparticles 76 and iron oxide nanoparticles 29 with negative zeta potentials were able to effectively absorbed on MG-63, A549, and HeLa cells.…”

“…36 It was addressed that highly negative zeta potential contributed to accumulate on Ca 2+ ions, which was conductive to bone regeneration, thus enhanced the bioactivity of the nanoparticle. 30 On the contray, low zeta potential would lead to aggregation or coagulation of nanoparticles, favored by interparticle interaction. To summary, the surface electronegativities and zeta potential could be taken as one of the descriptors in understanding the aggregation and biological functions of CaP particles.…”

“…It has also been found that the pH condition has great influence on the intrinsic physicochemical characteristics of various CaP samples, including adsorption of organic acids 26 , phase composition 27 , morphology and crystal size 28 . Moreover, zeta potentials were affected by pH values for many nanoparticles, such as iron oxide nanoparticles, 29 Ag@HA, 30 F-Cl@HA, 31 and the complexes of HA with the additives of citric acid 32 , oxalic acid 33 and malic acid 34 . Such negative zeta potentials of nanoparticles were proposed to favor osseointegration, apatite nucleation, and inhibition of tumor cell proliferation.…”

Synthesis of polypyrrole nanoparticles and their applications in electrically conductive adhesives for improving conductivity

“…It was found that a larger absolute value of zeta potential reects that there are more positive charges or negative charges on the surface of suspended solids, which can stabilize powders in the environment. [42][43][44] The zeta potential of silver akes (0.2 g L À1 ) suspended in water was measured to be À35.6 mV, while the zeta potential of PPy NPs is +37.7 mV (Fig. 6a).…”
