Conventional plasmonic approaches typically enhance chirality at the cost of amplifying achiral attraction and heating. Here, we overcome this trade\u2010off by exploiting longitudinal Mie resonances in silicon nanodisks. By employing an azimuthally\u2013radially polarized beam (ARPB) illumination, we excite longitudinal Mie resonances, with strong optical chirality gradients and comparatively uniform electric field intensities. Specifically, magnetic quadrupole (MQ) resonances effectively decouple enantioselective forces from the achiral background, providing uniquely favorable conditions for enantioselective optical trapping. Combining numerical simulations with Kramers' escape\u2010rate theory, we demonstrate a robust and highly selective trapping system that is also experimentally accessible. We predict trapping selectivity ratios above 100 for particles with Pasteur parameters  and maintain selectivities above 2 even for weakly chiral analytes . These results establish longitudinal Mie resonances in high\u2010index dielectric nanostructures as a promising noninvasive platform for all\u2010optical chiral analysis and enantiomer separation.<\/jats:p>","DOI":"10.1002\/nap2.70207","type":"journal-article","created":{"date-parts":[[2026,7,18]],"date-time":"2026-07-18T08:51:06Z","timestamp":1784364666000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Enhanced Enantioselective Optical Trapping Enabled by Longitudinal Mie Resonances in Silicon Nanodisks"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9363-187X","authenticated-orcid":false,"given":"Guillermo","family":"Serrera","sequence":"first","affiliation":[{"name":"Group of Optics Department of Applied Physics University of Cantabria  Santander Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7531-7828","authenticated-orcid":false,"given":"Pablo","family":"Albella","sequence":"additional","affiliation":[{"name":"Group of Optics Department of Applied Physics University of Cantabria  Santander Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,18]]},"reference":[{"key":"e_1_2_10_2_1","article-title":"Memoire Sur La Relation Qui Peut Exister Entre La Forme Cristalline Et La Composition Chimique, Et Sur La Cause De La Polarisation Rotatoire","volume":"26","author":"Pasteur L.","year":"1848","journal-title":"Comptes Rendus Hebdomadaires des S\u00e9ances de L\u2019Academie des Sciences"},{"key":"e_1_2_10_3_1","volume-title":"The Molecular Tactics of a Crystal","author":"Kelvin W.
