Table 1:

Average cell viability (All four cell lines) comparison between the non-transferrin and transferrin conjugated samples at their lowest concentrations. All the abbreviations are as below, C-dots-epirubicin (C-dots-epi), C-dots-temozolomide (C-dots-temo), C-dots-epirubicin+temozolomide (C-dots-epi+temo), C-dots-transferrin-temozolomide (C-TT), C-dots-transferrin-epirubicin (C-dots-epi), C-dots-transferrin-epirubicin-temozolomide (C-DT)
