The zeta potential of aluminum hydroxide colloidal particles,the inactivated NDV and the nano-aluminum adjuvant NDV are +48.16 mV,?13.8 mV and +39.97 mV,respec-tively. The nano-aluminum adjuvant vaccine was transparent and stable without precipitate,whereas the conventional aluminum ad-juvant vaccine was turbid and a white precipitate was visible soon. The hemagglutination inhibition (HI) titers of the nano-aluminum adjuvant group were generally higher than those of the conventional aluminum group except the titer on day 29. The results show that the nano-aluminum adjuvant has better stability and higher levels of antibodies for a longer time than the conventional aluminum adjuvant.展开更多
