Comprised of chemically distinct blocks with differing architectures, these unique polymer frameworks exhibit properties that surpass those of conventional amphiphilic polymers. However, a lack of synthetic feasibility has hindered the widespread adoption of amphiphilic HBCs due to challenges posed by the distinct solubility of the blocks, the steric effects of the branched block on copolymerization and purification of end products, and the difficulty of preparing amphiphilic HBCs. Herein, we report the use of aqueous reversible addition-fragmentation chain transfer (RAFT) polymerization to form amphiphilic HBCs and assess their potential as biomaterials for theranostic applications. Comprised of chemically distinct blocks with differing architectures (i.e., dendritic and grafted\/linear), these unique polymer frameworks were strategically designed to self-assemble into nanoparticles ideal for simultaneous bioimaging and therapy. The synthesis, physicochemical characterization, and in vitro cell viability of a library of dendritic HBCs and their resulting nanoparticles are discussed. Microscopy (TEM) and dynamic light scattering (DLS) analyses support the formation of aqueous dispersions, yielding polymeric nanoparticles with sizes < 120 nm. The resulting polymer hybrids and their nanoparticles exhibited minimal cell toxicity and dual imaging and therapeutic potential. Results indicate that these polymers and their nanoparticles exhibit properties surpassing those of conventional amphiphilic polymers. This study exemplifies the effect of polymer topology on nanomaterial properties and expands the design space of RAFT polymerization in biomedical research.", "occurrence_notes":null, "guid":"151574-21911781@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/151574", "building_id":"1000158", "building_name":"Chemistry Dow Lab", "campus_maps_id":"34", "room":"CHEM 1640", "location_name":"Chemistry Dow Lab", "has_livestream":0, "cost":"", "tags":["Chemistry","Chemical Education"], "website":"https:\/\/chemistry.osu.edu\/people\/watkins.891", "sponsors":[ { "group_name":"Department of Chemistry", "group_id":"3761", "website":"https:\/\/lsa.umich.edu\/chem" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21911781 } , "152055-21912772": { "datetime_modified":"20260930T173806", "datetime_start":"20261005T160000", "datetime_end":"20261005T170000", "has_end_time":1, "date_start":"2026-10-05", "date_end":"2026-10-05", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"ISRMT Seminar: Extremal Problems Motivated by Focusing NLS Condensates", "occurrence_title":"", "combined_title":"ISRMT Seminar: Extremal Problems Motivated by Focusing NLS Condensates: Alexander Tovbis (University of Central Florida)", "event_subtitle":"Alexander Tovbis (University of Central Florida)", "event_type":"Presentation", "event_type_id":"16", "description":"Abstract: Soliton gases for integrable systems is a rapidly developing new area in the theory of nonlinear waves. For a given spectral support set, a soliton gas of maximal average intensity is called soliton condensate. A spectral support set for a fNLS soliton condensate is often represented by a finite collection of points (anchors) E in the upper half plane H, connected with each other and\/or with the real axis by some set of (Schwarz symmetrical) arcs. Given a set of anchors E, a natural question is to find a collection of such arcs that produces fNLS soliton condensate of minimal average intensity. That leads to a modification of the well-known Chebotarev\u2019s continuum problem, which consists in finding a continuum K \u2282 C of minimal logarithmic capacity that contains a given set of anchors E \u2282 C. In this talk, we discuss our solution to the modified Chebotarev\u2019s problem, where E and K are subsets of the upper half plane H and where we minimize the Dirichlet energy of H \\ K instead of the logarithmic capacity of K.
