Decoding the Conformation of Polylactic Acid in Block Copolymer Micelles Muñoz López, José María Tuveri, Gian Marco Barbieri, Valentino Basile, Marco Cosenza, V. Lorenz, Christian D. Ruiz-Perez, Lorena Battaglia, Giuseppe Polimerització Copolímers Polymerization Copolymers Understanding how molecular features dictate the self-assembly of amphiphilic block copolymers into well-defined nanostructures is essential for the rational design of advanced soft materials. However, the large number of interdependent parameters involved, such as particle size, aggregation number, interfacial curvature, and molecular weight, makes it challenging to establish general design principles. Here we establish a scaling-based framework for PEG-<em>b</em>-PLA micelles with a fixed hydrophilic–hydrophobic ratio. Systematic variation of molecular weights enables precise control of micelle size and aggregation number, quantified by DLS, cryo-TEM, and MALS. 2026-03-27T09:27:48Z 2026-03-27T09:27:48Z 2026-01-28 2026-03-27T09:27:48Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0002-7863 https://hdl.handle.net/2445/228558 767404 eng Reproducció del document publicat a: https://doi.org/10.1021/jacs.5c19227 Journal of the American Chemical Society, 2026, vol. 148, num.5, p. 4839-4843 https://doi.org/10.1021/jacs.5c19227 cc-by (c) Muñoz López, José María et al., 2026 https://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess 5 p. application/pdf American Chemical Society Articles publicats en revistes (Química Inorgànica i Orgànica)
