They can stimulate innate immunity and promote adaptive immune responses by exhibiting different pathogen associated-molecular patterns (PAMPs) for a large number of immunogenic antigens with adjuvant properties [83] .

Document: The use of bacterial membranes as vaccination materials has gained considerable interest. They can stimulate innate immunity and promote adaptive immune responses by exhibiting different pathogen associated-molecular patterns (PAMPs) for a large number of immunogenic antigens with adjuvant properties [83] . Camouflaging NPs with covering bacterial membranes results in the preservation of bacterial characteristics, and thus helps in mimicking natural antigen presentation by bacteria to the immune system. Gao et al. [83] reported a bacterial membrane coated NP for antibacterial therapy, in which gold NPs were coated with bacterial outer vesicles. In this study, they chose E. coli bacteria, obtained its outer membranes, and coated gold NPs of 30 nm size with them; they found that this could induce rapid activation and DC maturation in the lymph nodes. Further, vaccination with these NPs produced long-lasting and robust antibody responses [83] .
