Compared with free docetaxel (DTX), both Tf-modified DTX NCs (Tf-DTX-NCs) and unmodified DTX NCs displayed rapid drug release behavior, but Tf-DTX-NCs showed significantly higher cellular uptake for 2-h incubation and higher toxicity for 72-h incubation than DTX NCs in human non-small cell lung cancer (NSCLC) cell line A549 [97]. Here, TF is linked to non-small cell lung carcinoma.
