Consequently, independent control over micelle width, length, and stiffness remains challenging. A supramolecular polymerization\u2010induced self\u2010assembly (PISA) strategy using a bis\u2010urea core template was recently shown to robustly yield wormlike micelles across a wide range of core block lengths; however, the resulting FM lengths remained highly polydisperse. Herein, we investigate two strategies to tune the contour length: (\n                    <jats:bold>\n                      <jats:italic>i<\/jats:italic>\n                    <\/jats:bold>\n                    ) Blending in polymer without the bis\u2010urea sticker and (\n                    <jats:bold>\n                      <jats:italic>ii<\/jats:italic>\n                    <\/jats:bold>\n                    ) post\u2010micellization sonication. Unexpectedly, incorporating non\u2010sticker polymer can increase the contour length. Transmission electron microscopy (TEM), fluorescence cross\u2010correlation spectroscopy (FCCS), and high\u2010resolution atomic force microscopy (AFM) were used to elucidate the key factors contributing to this peculiar self\u2010assembly mechanism. Sonication\u2010induced cleavage led to shortening of the particles and narrower polydispersity in length. Combined, the two strategies provide access to a wide range of anisotropic micelles with accessible aspect ratios ranging from 1 to &gt;150. Considering their long\u2010term (colloidal) stability, the presented system is an ideal model to study the effect of micellar anisotropy, for example, in drug delivery relevant scenarios.\n                  <\/jats:p>","DOI":"10.1002\/smll.74648","type":"journal-article","created":{"date-parts":[[2026,7,17]],"date-time":"2026-07-17T10:27:12Z","timestamp":1784284032000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Tuning the Length of Filomicelles Prepared Via Templated Polymerization\u2010Induced Self\u2010Assembly"],"prefix":"10.1002","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6994-8228","authenticated-orcid":false,"given":"Eleonora G.","family":"Hochreiner","sequence":"first","affiliation":[{"name":"Division of Pharmaceutics, Utrecht Institute For Pharmaceutical Sciences, Faculty of Science Utrecht University  Utrecht the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-0302-623X","authenticated-orcid":false,"given":"Wiktoria","family":"Pioru\u0144ska","sequence":"additional","affiliation":[{"name":"Division of Pharmaceutics, Utrecht Institute For Pharmaceutical Sciences, Faculty of Science Utrecht University  Utrecht the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ga\u00eblle","family":"Mellot","sequence":"additional","affiliation":[{"name":"Institut Parisien de Chimie Mol\u00e9culaire (IPCM) Centre national De La Recherche Scientifique (CNRS) Sorbonne Universit\u00e9  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8621-623X","authenticated-orcid":false,"given":"Bence","family":"Feh\u00e9r","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering and Chemistry, Institute for Complex Molecular Systems (ICMS) Eindhoven University of Technology  Eindhoven The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean\u2010Michel","family":"Guigner","sequence":"additional","affiliation":[{"name":"Institut De Min\u00e9ralogie, De Physique des Mat\u00e9riaux et De Cosmochimie (IMPMC), Centre national De La Recherche Scientifique (CNRS) Sorbonne Universit\u00e9  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-7750-2425","authenticated-orcid":false,"given":"Viktoriia","family":"Drebezghova","sequence":"additional","affiliation":[{"name":"Interfaces, Confinement, Mat\u00e9riaux et Nanostructures (ICMN), Centre national De La Recherche Scientifique (CNRS) Universit\u00e9 D'orl\u00e9ans  Orl\u00e9ans France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9528-2797","authenticated-orcid":false,"given":"Christophe","family":"Sinturel","sequence":"additional","affiliation":[{"name":"Interfaces, Confinement, Mat\u00e9riaux et Nanostructures (ICMN), Centre national De La Recherche Scientifique (CNRS) Universit\u00e9 D'orl\u00e9ans  Orl\u00e9ans France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4210-5241","authenticated-orcid":false,"given":"Cornelus F. van","family":"Nostrum","sequence":"additional","affiliation":[{"name":"Division of Pharmaceutics, Utrecht Institute For Pharmaceutical Sciences, Faculty of Science Utrecht University  Utrecht the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6047-5900","authenticated-orcid":false,"given":"Tina","family":"Vermonden","sequence":"additional","affiliation":[{"name":"Division of Pharmaceutics, Utrecht Institute For Pharmaceutical Sciences, Faculty of Science Utrecht University  Utrecht the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9391-4917","authenticated-orcid":false,"given":"Jutta","family":"Rieger","sequence":"additional","affiliation":[{"name":"Institut Parisien de Chimie Mol\u00e9culaire (IPCM) Centre national De La Recherche Scientifique (CNRS) Sorbonne Universit\u00e9  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9024-3927","authenticated-orcid":false,"given":"Bas G.
