Photosensitizer-loaded dendrimer-modified multi-walled carbon nanotubes for photodynamic therapy

Abstract summaryPolyamidoamine dendrimer modified multi-walled carbon nanotubes (dMNTs) have been explored as new vehicles to deliver the photosensitizer 5-aminolevulinic acid (5-ALA) to tumor MGC-803 cells. Intense fluorescence of protoporphyrin IX (PpIX) was monitored in the cytoplasm of MGC-803 c
