Figure 9:

Fluence dependence of most photoactive compounds 1-nT and 2-nT (n=3,4) against amelanotic SK-MEL-28 human cells. Fluence ranged from 0 (dark) to 100 J cm⁻² at 18 mW cm⁻² for light treatments using (a) red 633 nm and (b) green 523 nm. Reported log (EC₅₀ ± SEM) values were taken from log-logistic fits. SEM = standard error of the mean. * Values from separate experiment as reported in Figure 8.
