Boron nitride nanotubes functionalized with mesoporous silica for intracellular delivery of chemotherapy drugs

Boron nitride nanotube (BNNT)@ mesoporous silica hybrids with controllable surface zeta potential were fabricated for intracellular delivery of doxorubicin. The materials showed higher suspension ability, doxorubicin intracellular endocytosis efficiency, and LNcap prostate cancer cell killing ability compared with naked BNNTs.
