The drug concentrations required to inhibit cell growth by 50% (IC50) at 2 h or 24 h in SKOV3 or OVCAR3 cells cultured in monolayer (2D) or spheroids (3D) and after light exposure (690 nm; 10 J·cm-2). Data represent the mean ± SD (SKOV3, n = 3; OVCAR3, n = 4, except # n = 2). Each independent experiment was performed in triplicate.
