SpletThe final hybrid NPs were collected, washed and redispersed in PBS buffer at pH 7.4. For the modified electrostatic assembly approach, PEI stabilized AIS/ZnS QDs or SPIO NPs were used for further assembly. Briefly, AIS/ZnS-PEI QDs (0.1 mL) was added into a solution of SPIO-DX NPs (0.5 mg/mL) and the mixture was stirred for 20 min. Splet27. maj 2024 · 1 Answer.
