Objective:To prepare amphotericin B-polybutylcyanoacrylate-loaded nanoparticle(AmB-PBCA-NP) and to assess their ability to pass the blood-brain barrier.Methods: AmB-PBCA-NP was prepared by incubation,with the surface modified by polysorbate 80.High-performance liquid chromatography(HPLC) method was established using acetonitrile and water(4060,4% of acetic acid) as mobile phase;detection was done at 405 nm.Mice were divided into 3 groups: AmB-injected,AmB-lipid-injected,and AmB-PBCA-NP-injected group.Brain...
