Anti-CD133-grafted single-walled carbon nanotubes as doxorubicin carrier.

ABSTRACT:

Background

Advances in nanomedicine have spurred interest in antibody-conjugated carbon nanotubes for targeted cancer therapy. CD133, a marker enriched in chemoresistant cancer stem cells, presents a strategic target for precision drug delivery. This study explores functionalized single-walled carbon nanotubes (SWCNTs) as dual-action platforms for enhanced doxorubicin (DXR) delivery and CD133-specific targeting.

Methods

Two nano formulations-SWCNT-Ab/DXR (antibody-functionalized) and SWCNT-PEG-Ab/DXR (pegylated antibody-functionalized)-were engineered to encapsulate DXR. Release profiles, cytotoxicity, and apoptosis were assessed in CD133⁺ HT-29 colorectal cancer cells and CD133^- CHO control cells. Computational modeling included DFT-D structural optimi
