In their study, the authors tested the effects of a prototypic antioxidant of the class of manganese
porphyrins in an established preclinical model for aqueous-deficient dry-eye disease and found that their formulation was superior to the therapeutic effect observed by the current clinical standard of care, cyclosporine emulsion.
The first one points out the formation of the complex between
porphyrin and Ag nanoparticles and the second one is in connection with the strong shifting to the red of the hybrid band and producing its widening up to 650 nm, probably due to an electrostatic equilibrium between materials with opposite charges.
The increase in fluorescence emission is probably related to the displacement of the magnesium atom from the
porphyrin ring.
An isosbestic point is detectable at 645 nm on the last Q band of the
porphyrin (Figure 6(b)).

The yellow plane represents the mean
porphyrin plane created through pyrrolic N atoms.
Clinically important features of
porphyrin and heme metabolism and the porphyrias.
Here we consider a third class of biomolecules which exhibit phase conjugation behavior as alternative locations for the holographic grating than that formed by
porphyrin networks.
