Table 1. Indicative values of fluencesa characterizing TPA compounds based on morphological and biochemical criteria.
1-PE: one-photon excitation; 2-PE: two-photon excitation.
aFluences were calculated for a TPA concentration of 2 μM. The symbol “<” means that fluence was measured under continuous illumination and then corresponds to an upper limit value.
