    Versatile formation of supported lipid bilayers from bicellar mixtures of phospholipids and capric acid by Sut, Tun Naw, Yoon, Bo Kyeong, Park, Soohyun, Jackman, Joshua A., Cho, Nam-Joon

    Published 2021
    “…Quartz crystal microbalance-dissipation, epifluorescence microscopy, and fluorescence recovery after photobleaching experiments were conducted to characterize lipid concentration-dependent bicelle adsorption onto silicon dioxide surfaces. We identified that uniform-phase SLB formation occurred independently of total lipid concentration when the ratio of long-chain phospholipid to capric acid molecules (“q-ratio”) was 0.25 or 2.5, which is superior to past results with lauric acid- and monocaprin-containing bicelles in which cases lipid concentration-dependent behavior was observed. …”
