Simple cyclic disulfides under high tension mediate the uptake of giant substrates, that is, liposomes and polymersomes with diameters of up to 400 nm, into HeLa Kyoto cells. To place them at the surface of the vesicles, the strained disulfides were attached to the head‐group of cationic amphiphiles. Bell‐shaped dose response curves revealed self‐activation of the strained amphiphiles by self‐assembly...
The objective of the study was to explore the potential of ring tension in cyclic disulfides for thiol‐mediated cellular uptake. Fluorescent probes that cannot enter cells were equipped with cyclic disulfides of gradually increasing ring tension. As demonstrated by flow cytometry experiments, uptake into HeLa Kyoto cells increased with increasing tension. Differences in carbon‐sulfur‐sulfur‐carbon...
