Membranes, Volume 13, Issue 4

2023 April - 88 articles

Cover Story: In this article, we discuss the possible mechanism of fast cargo release from a new type of pH-sensitive liposomes with embedded ampholytic molecular switch (AMS, 3-(isobutylamino)cholan-24-oic acid) with carboxylic anionic groups and isobutylamino cationic ones attached to the opposite ends of the steroid core. AMS-containing liposomes have demonstrated excellent speed of the encapsulated substance release under altering the pH of outer solution, but the exact mechanism of the switch action has not yet been accurately determined. Here, we report on the details of fast cargo release based on data obtained via ATR-FTIR spectroscopy as well as atomistic molecular modeling. The findings of this study are promising for potential biomedical application of AMS-containing pH-sensitive liposomes. View this paper
