Polymerization confirmation.

Absorbance as a function of wavelength (nm) for the DMPC:DC8,9PC:DOTAP (1:1:0.2), DMPC:DC8,9PC:MCL (1:1:0.2) and DMPC:DC8,9PC:SA (1:1:0.2) mixtures, prepared with the copolymerization methodology, after 20 UV irradiation cycles. Peaks observed around 480 and 520 nm are indicative of polymer formation.
