This work establishes a full\u2010field analysis framework for designing plasmonic nanoaperture tweezers under coherent illumination and experimental restrictions. We studied the plasmonic responses of three complementary plasmonic platforms\u2014nanohole, nanohole\u2013nanodisk, and cavity\u2010coupled nanohole\u2013nanodisk arrays\u2014and their nanotrapping performance on dielectric and metallic nanoparticles using three\u2010dimensional electromagnetic simulations and Maxwell stress tensor calculations. The results show that the force landscape in the particle volume depends strongly on the plasmonic resonance strength, the nanoparticle material, and the interaction with the target nanoparticle. In particular, we found that the cavity\u2010coupled plasmonic array represents the most promising nanotrapping platform, capable of stable nanotrapping of metallic nanoparticles even under low power budgets and modest optical systems. Finally, we introduce a multi\u2010criteria figure of merit (FoM) to compare trade\u2010offs among trap stability, particle detuning effects, optical load, and nanoparticle material response. These results provide design guidance for compact, low\u2010input\u2010power plasmonic nanotweezer devices.<\/jats:p>","DOI":"10.1002\/nap2.70318","type":"journal-article","created":{"date-parts":[[2026,10,12]],"date-time":"2026-10-12T03:41:03Z","timestamp":1791776463000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Engineering Low\u2010Power Cavity\u2010Coupled Plasmonic Nanotweezers"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-5634-1977","authenticated-orcid":false,"given":"Nasrin","family":"Abdollahi","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering North Carolina State University  Raleigh North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0648-5921","authenticated-orcid":false,"given":"Abraham","family":"V\u00e1zquez\u2010Guardado","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering North Carolina State University  Raleigh North Carolina USA"},{"name":"Center for Advanced Self\u2010Powered Systems of Integrated Sensors and Technologies (ASSIST) North Carolina State University  Raleigh North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,11]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1063\/1.1785844"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.79.645"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.nanolett.2c04492"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1364\/OL.11.000288"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/s43586\u2010021\u201000021\u20106"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1242\/jcs.259355"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1038\/srep01759"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41567\u2010021\u201001357\u20102"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467\u2010024\u201045162\u2010w"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsphotonics.8b00176"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1063\/1.464105"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/nnano.2014.24"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41377\u2010019\u20100146\u2010x"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsnano.7b07914"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0006\u20103495(95)80396\u20106"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1021\/nl203719v"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1039\/C4AN02213K"},{"key":"e_1_2_9_19_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.nanolett.8b00732"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.nanolett.0c00300"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.3390\/photonics10060623"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsphotonics.2c01986"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1364\/OE.510635"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.1002\/adom.202302603"},{"key":"e_1_2_9_25_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsnano.1c00466"},{"key":"e_1_2_9_26_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsphotonics.2c00231"},{"key":"e_1_2_9_27_1","doi-asserted-by":"publisher","DOI":"10.1038\/nphoton.2011.56"},{"key":"e_1_2_9_28_1","doi-asserted-by":"publisher","DOI":"10.1364\/OL.43.003413"},{"key":"e_1_2_9_29_1","doi-asserted-by":"publisher","DOI":"10.1038\/srep38086"},{"key":"e_1_2_9_30_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467\u2010018\u201004689\u20105"},{"key":"e_1_2_9_31_1","doi-asserted-by":"publisher","DOI":"10.1038\/nphys1422"},{"key":"e_1_2_9_32_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41467\u2010023\u201040549\u20107"},{"key":"e_1_2_9_33_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.optlaseng.2022.107001"},{"key":"e_1_2_9_34_1","volume-title":"Absorption and Scattering of Light by Small Particles","author":"Bohren C.
