<\/a>A common way to get elastic parameters from lipid membranes is to analyze the power spectra of some fields, like shape or director. But how do you define those? Turns out, details matter for the answer!<\/p><\/div>\n\t\t\t<\/div>![](\"http:\/\/research.phys.cmu.edu\/deserno\/wp-content\/uploads\/sites\/6\/2021\/07\/PT-2021-JCP-154-014704.png\")
<\/a>Beyond a certain stress asymmetry lipid membranes become stiffer. This could be related to the formation of finite gel domains in the compressed leaflet.<\/div>\n\t\t\t<\/div>![](\"http:\/\/research.phys.cmu.edu\/deserno\/wp-content\/uploads\/sites\/6\/2021\/07\/PT-2020-APLBioEng-4-041507.png\")
<\/a>You can build 3D nanostructures with molecular precision using DNA, and you can attach anchors to those that would bind them to lipid membranes. Here we review how this is done, and what applications this makes possible.<\/p><\/div>\n\t\t\t<\/div>![](\"http:\/\/research.phys.cmu.edu\/deserno\/wp-content\/uploads\/sites\/6\/2021\/07\/PT-2020-JCTC-16-7195.png\")
<\/a>Our widely used 3-bead solvent free lipid Cooke model is a very efficient way to simulate fluid elastic membranes. But it has one down side: lipids flip-flop too rapidly, which prevents us from simulating asymmetric membranes. Here's how we fix this.<\/p><\/div>\n\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\n\t\t\t<\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":4,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"class_list":["post-17","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/research.phys.cmu.edu\/deserno\/wp-json\/wp\/v2\/pages\/17","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/research.phys.cmu.edu\/deserno\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/research.phys.cmu.edu\/deserno\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/research.phys.cmu.edu\/deserno\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/research.phys.cmu.edu\/deserno\/wp-json\/wp\/v2\/comments?post=17"}],"version-history":[{"count":37,"href":"https:\/\/research.phys.cmu.edu\/deserno\/wp-json\/wp\/v2\/pages\/17\/revisions"}],"predecessor-version":[{"id":553,"href":"https:\/\/research.phys.cmu.edu\/deserno\/wp-json\/wp\/v2\/pages\/17\/revisions\/553"}],"wp:attachment":[{"href":"https:\/\/research.phys.cmu.edu\/deserno\/wp-json\/wp\/v2\/media?parent=17"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
