Web6 de abr. de 2024 · Here, we construct amphiphile-nanomotifs purely from DNA, and achieve similar size and shape control for phase-separated droplets formed from fully synthetic, self-interacting DNA-nanomotifs. Low amphiphile concentrations induce rounding of droplets, followed by splitting and, ultimately, full dispersal at higher concentrations. WebThe continued fusion of newly formed lipid droplets with almost-completed droplets at the cell surface also explains the long-standing observation that pulse-radiolabeling of the mouse mammary gland in vivo with long-chain fatty acids leads to the rapid acquisition of a small fraction of the radiolabel in secreted lipid droplets, even though most of the …
