Fluorescence microscopy images of the internalization of the two nanoconstructs. a lymphocytes, b Daudi and c HL60 with TNH at 24 h, d lymphocytes, e Daudi and f HL60 with TNH^CD20 at 24 h, g lymphocytes, h Daudi and i HL60 with TNH at 48 h, j lymphocytes, k Daudi and l HL60 with TNH^CD20 at 48 h. Green represents the WGA488-labelled cells’ membranes, blue the secondary antibody of the TNH^CD20 nanoconstruct, purple the WGA647-labelled EVs and red the Atto550-lebelled ZnO NCs. Scale bar: 10 μm
