Internalization investigations on SH-SY5Y derived neurons, C8D1A astrocytes, and U87 MG cells treated for 24 h with 100 μg/ml of BNNTs with different coatings. A) ICP investigations on boron content inside cell cultures (* p < .05); B) representative flow cytometry fluorescence data for cells after treatment with DiO-stained BNNTs: for each distribution, populations of BNNT-positive cells are highlighted in red; C) summary of % of BNNT-positive cells for each experimental condition (* p < .05).
