Stability of Chlorophyll Monomer Incorporated into Cremophor EL Nano-Micelles under Dark and Moderate Light Conditions.

In this paper, stability of chlorophyll monomers encapsulated into the Cremophor EL nano-micelles was studied under dark and moderate light conditions, typical of a room with natural or artificial lighting, in the presence of oxygen. The pigment stability against visible light was determined using the dynamic light scattering and molecular spectroscopy (UV-Vis absorption and stationary fluorescence) methods. Chlorophyll , at the molar concentration of 10 M, was dissolved in the 5 wt% Cremophor emulsion for comparison in the ethanolic solution.
