Fig. 2. UV-Vis spectrophotometry analysis of liposomes and mechanoresponsive-liposomes prior and following ultrasonication. Spectra shown for ‘control’ and liposomes with 20 and 40 mol% content of cholesterol with incorporated either spiro I or spiro II compounds. Suspension of liposomes exposed to 1 MHz ultrasonication for 6 minutes and UV-Vis analysis performed immediately following exposure.
