Carbon nanotube (CNT)-based delivery systems for peptides and proteases. (A) SEM images of calcium phosphate cement (CPC)–MWCNT–Z-Leu-Leu-Leu-al (MG132). (B) The luciferase assay shows that MG132 released from CPC or CPC–MWCNT inhibited TNF-α-induced NF-κB activation and osteoclast differentiation. (C) Schematic diagram of CNT–poly(lactide-co-glycolide) (PLGA) conjugate fabrication and cell-to-cell delivery. (D) Penetration of CNT–PLGA–proteins into osteosarcoma cells cultured in CNT–PLGA–fBSA (fluorescent bovine serum albumin) (a,b) and CNT–PLGA–BSA penetrating the osteosarcoma cell (c,d).
