Abstract:

Aluminum nanopowders(ALEX) were prepared by electrical explosion and their effects of immune enhancing and tumor prevention were verified. The ALEX with well-dispersion were synthesized by electrical explosion of wires method, combing with carboxyl group polymer ligand reaction. The antigenic protein ovalbumin(OVA) and peptide was grafted onto ALEX surface by physical electrostatic adsorption. Fourier transform infrared spectroscopy demonstrated the grafting of antigen to ALEX. The immune enhancing effect of ALEX was verified: in vitro experiments showed that ALEX could improve the antigen presentation function of dendritic cells and the quantitative detection of antibodies in the serum of mice after immunization showed that ALEX could significantly increase the titer of antigen-specific antibodies. Finally, the tumor vaccine containing ALEX was proved to be effective for tumor prevention using mouse melanoma model.
