WebThis research examines the effect of both PEI concentration and molecular weight (MW) on dispersing LiFePO₄ and Super P C45 in multicomponent aqueous suspensions. It is demonstrated that the optimal conditions for obtaining stable suspensions with minimal agglomerate size are 1.5wt% PEI with MW=2000gmol⁻¹ and 5.0wt% PEI with … WebNext, we investigated the surface charge (zeta potential) of the formulated NPs. The single QDs had a negative charge of about −24 mV due to the carboxylic groups located on the surface, because the PEI-containing primary and secondary amine groups had a mean positive charge of +28 mV, and the miR-26a expression vector had a negative surface …
