ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,447,175, issued on Oct. 21, was assigned to Purdue Research Foundation (West Lafayette, Ind.).
"Polymer lung surfactants" was invented by You-Yeon Won (West Lafayette, Ind.) and Hyun Chang Kim (West Lafayette, Ind.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Disclosed herein are fully synthetic polymer-based lung surfactant materials, for the first time, as next generation SRT. In vitro studies on these polymer lung surfactants show that the candidate materials effectively mimic the surface tension controlling properties of currently marketed natural lung surfactants. Further, the polymer lung surfactants have strong protein resistance, which makes t...
