For nanoparticle synthesis, the TPP–PEG–biotin film layer was hydrated with 900 μl of PBS (pH 7.4) and 100 μl of DMSO. Then the solution mixture was sonicated for 15 min, and uniform sized self-assembled TPP–PEG–biotin NPs were obtained slowly. The NPs were collected by centrifugation at 15[thin space (1/6-em)]000 rpm using a TJ-25 centrifuge (Beckman Coulter). The characterization of TPP–PEG–biotin SANs was done by TEM and SEM. The stock was diluted with PBS (pH 7.4) and used for in vitro experiments.
