Figure 5
CLSM images of 2D cryosections of brain spheroids after 24 h of incubation with green-fluorescent FAM-labelled gold nanoparticles (Au-Click-FAM) and dissolved FAM-alkyne. The spheroids were cryopreserved in liquid nitrogen, sectioned (thickness 7 µm) and stained with DAPI for 10 min. Scale bars 200 µm.
