Preparation and characteristics of DP-AD. a Schematic of the two-step preparation of DP-AD. b Screening of the best N/P molar ratios ranging from 1 to 16 by 1% agarose gel electrophoresis. The upper and lower images indicated hydrophilic DP-AD1 and amphipathic DP-AD7, respectively. c TEM images of AD1 and AD7. d The size of ADs in dd H2O (white columns) and diluted with equal volume of M–H broth (black columns). e TEM images of DP-AD1 and DP-AD7. f The size of DP-AD in dd H2O (white columns) and diluted with equal volume of M–H broth (black columns), and zeta potential (blue line) of DP-AD in dd H2O determined by DLS. Bar = 200 nm
