Figure 2From: Antitumor activity of photodynamic therapy performed with nanospheres containing zinc-phthalocyanineNormalized fluorescence emission spectrum of ZnPcS 4 (-) and ZnPcS 4 -AN (-) in PBS. ZnPcS4-AN presents a small blue shift of the peak emission in comparison to the characteristic peak emission of ZnPcS4at 690 nm.Back to article page
