Table 1.

Nanoparticle size (diameter) and surface charge of empty and 5, 10, 15, 20-tetraphenyl-21H, 23H-porphyrine-(TPP)-loaded particles determined by dynamic light scattering. Z-Average (Z-Ave) describes the mean size of all particles in the sample; the number represents the size of the particles forming the biggest population in the sample.
