Figure 3From: Effect of single-walled carbon nanotubes on tumor cells viability and formation of multicellular tumor spheroids Effect of SWCNTs on the number of alive and dead cells. In adhesion and suspension fractions (A) and cell viability compare with control (B). The number of alive/dead cells was counted due to usage of trypan blue. Cell viability was analyzed by MTT assay. *p < 0.01, #p < 0.05.Back to article page
