Fig. 8From: Overcoming the blood–brain barrier for the therapy of malignant brain tumor: current status and prospects of drug delivery approachesApplication of organic nanocarriers for brain tumor therapy: A Characterization of albumin-based NPs with the following histological analysis, demonstrating tumor inhibition effect (scale bar = 1 μm). Adapted with permission from Ref. [238]. B Characterization of PLA-based NPs and their biodistribution in the brain (scale bar = 200 nm). Adapted with permission from Ref. [247]. C SEM images of PLGA-based NPs and MR images before and after the therapy (scale bar = 1 μm). Adapted with permission from Ref. [248]. D AFM image of liposomes, in vivo fluorescent distribution, and histological analysis, demonstrating the tumor inhibition effect. Adapted with permission from Ref. [266]Back to article page
