Cell Uptake and Validation of Novel PECs for Biomedical Applications

Figure 4

Cell viability assayed by cellular membrane damage assessment using the Trypan Blue exclusion test of PECs in (a) HeLa and (b) BJ cells. Percent cell viability versus PECs concentration for 24 to 48 to 72 hours. Representative measurements of three distinct sets of data have been reported (t-Student test, P < 0.05).
