In this Letter, we investigate the two-dimensional diffusion of smoothly curved\r\ncolloidal rods—also known as colloidal bananas—as a function of their opening angle α. We measure the\r\ntranslational and rotational diffusion coefficients of the particles with opening angles ranging from 0◦ (straight\r\nrods) to nearly 360◦(closed rings). In particular, we find that the anisotropic diffusion of the particles varies\r\nnonmonotonically with their opening angle and that the axis of fastest diffusion switches from the long to the\r\nshort axis of the particles when α> 180◦. We also find that the rotational diffusion coefficient of nearly closed\r\nrings is approximately an order of magnitude higher than that of straight rods of the same length. Finally, we\r\nshow that the experimental results are consistent with slender body theory, indicating that the dynamical behavior\r\nof the particles arises primarily from their local drag anisotropy. These results highlight the impact of curvature\r\non the Brownian motion of elongated colloidal particles, which must be taken into account when seeking to\r\nunderstand the behavior of curved colloidal particles."}],"_id":"22212","arxiv":1,"date_created":"2026-06-30T06:32:12Z","article_number":"L042602","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2211.07274"}],"article_type":"letter_note","publication":"Physical Review E","doi":"10.1103/physreve.107.l042602","external_id":{"arxiv":["2211.07274"]},"scopus_import":"1","issue":"4","month":"04","has_accepted_license":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","type":"journal_article","date_published":"2023-04-21T00:00:00Z","publisher":"American Physical Society","author":[{"first_name":"Justin-Aurel","full_name":"Ulbrich, Justin-Aurel","last_name":"Ulbrich"},{"id":"492def71-6250-11f0-b278-d41dbd241b62","last_name":"Fernández-Rico","first_name":"Carla","full_name":"Fernández-Rico, Carla"},{"last_name":"Rost","full_name":"Rost, Brian","first_name":"Brian"},{"first_name":"Jacopo","full_name":"Vialetto, Jacopo","last_name":"Vialetto"},{"full_name":"Isa, Lucio","first_name":"Lucio","last_name":"Isa"},{"last_name":"Urbach","first_name":"Jeffrey S.","full_name":"Urbach, Jeffrey S."},{"last_name":"Dullens","full_name":"Dullens, Roel P.
