Reproducing such functions with synthetic materials remains a central challenge at the interface of polymer chemistry, supramolecular science, and chemical biology. In this seminar, I will present our efforts to construct synthetic membrane functions using polymer assemblies.\u0026nbsp;First, I will describe the development of polymer-based molecularly permeable vesicles, focusing on the mechanisms that govern membrane permeability and the molecular design principles required to control transmembrane transport. I will then introduce polymer-based artificial ion channels designed to mediate ion transport across lipid bilayers. Finally, I will discuss amphiphilic random copolymers that associate with lipid membranes to form polymer-rich domains. These membrane-associated polymer assemblies provide a platform for integrating molecular transport with catalytic transformation, thereby serving as synthetic analogues of multifunctional membrane proteins. \u0026nbsp;I will also highlight their extension toward cancer-related therapeutic applications.\u003C\/p\u003E\u003Cp\u003ETogether, these studies illustrate how polymer assemblies can be used to create programmable membrane functions, from molecular transport to chemical transformation, in biomimetic and biological environments.\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022https:\/\/people.research.gatech.edu\/julie-champion\u0022\u003EJulie Champion\u003C\/a\u003E, faculty host\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Ch5\u003E\u0022Polymer Assemblies for Synthetic Membrane Functions: From Permeable Vesicles to Molecular Transport and Transformation\u0022 - Tomoki Nishimura, Shinshu University, Japan\u003C\/h5\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"\u0022Polymer Assemblies for Synthetic Membrane Functions: From Permeable Vesicles to Molecular Transport and Transformation\u0022 - Tomoki Nishimura, Shinshu University, Japan"}],"uid":"36479","created_gmt":"2026-08-11 12:21:38","changed_gmt":"2026-08-11 13:56:50","author":"abowman41","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-08-31T10:00:00-04:00","event_time_end":"2026-08-31T11:00:00-04:00","event_time_end_last":"2026-08-31T11:00:00-04:00","gmt_time_start":"2026-08-31 14:00:00","gmt_time_end":"2026-08-31 15:00:00","gmt_time_end_last":"2026-08-31 15:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Petit Biotechnology Building (IBB), 315 Ferst Drive NW, Suddath Seminar Room 1128, Atlanta, GA 30332","extras":[],"groups":[{"id":"1292","name":"Parker H.
