Figure 6: A: The PNB lifetime-probability diagram for prostate cancer (C4-2B) cells treated with NSP-PSMA and NS-C225 gold conjugates, and exposed to different optical pulses (pump laser pulses 0.5 [email protected] mJ/cm2 at 532 nm and 787 nm). The rainbow mechanism corresponds to the sample shown with a solid rhomb (cells were treated with the two conjugates and two simultaneous laser pulses); B: the PNB lifetime-probability diagram for prostate cancer (C4-2B) cells shows the influence of the NP cluster content (the ratio of NSC225: NSP-PSMA) on the PNB parameters under excitation with one 0.5-ns laser pulse 532 [email protected] mJ/cm2 or 787 [email protected] mJ/cm2 (single wavelength excitation), and two simultaneous laser pulses - 532 nm and 787 nm (rainbow mechanism).
