Nanoplastics, in particular, have been shown to be difficult to detect in drinking water, requiring new capture technologies. In this work, we applied the acoustofluidic seed particle method to capture nanoplastics in an optimized, tilted grid of silica clusters even at the high flow rate of 5 mL\/min. Moreover, we achieved, using this technique, the enrichment of nanoparticles ranging from 500 nm to 25 nm as a first in the field. We employed fluorescence to observe the enrichment profiles according to size, using a washing buffer flow at 0.5 mL\/min, highlighting the size-dependent nature of the silica seed particle release of various sizes of nanoparticles. These results highlight the versatility of acoustic trapping for a wide range of nanoplastic particles and allow further study into the complex dynamics of the seed particle method at these size ranges. Moreover, with reproducible size-dependent washing curves, we provide a new window into the rate of nanoplastic escape in high-capacity acoustic traps, relevant to both environmental and biomedical applications.<\/jats:p>","DOI":"10.3390\/mi15121487","type":"journal-article","created":{"date-parts":[[2024,12,11]],"date-time":"2024-12-11T06:44:05Z","timestamp":1733899445000},"page":"1487","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["EchoTilt: An Acoustofluidic Method for the Capture and Enrichment of Nanoplastics Directed Toward Drinking Water Monitoring"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2675-9253","authenticated-orcid":false,"given":"Martim","family":"Costa","sequence":"first","affiliation":[{"name":"Science for Life Laboratory, Department of Protein Science, Division of Nanobiotechnology, KTH Royal Institute of Technology, 171 65 Solna, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liselotte","family":"van der Geer","sequence":"additional","affiliation":[{"name":"Science for Life Laboratory, Department of Protein Science, Division of Nanobiotechnology, KTH Royal Institute of Technology, 171 65 Solna, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel","family":"Joaquim","sequence":"additional","affiliation":[{"name":"Departamento de Bioengenharia, Instituto Superior T\u00e9cnico, 1049-001 Lisboa, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Hammarstr\u00f6m","sequence":"additional","affiliation":[{"name":"Science for Life Laboratory, Department of Applied Physics, KTH Royal Institute of Technology, 171 65 Solna, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Tanriverdi","sequence":"additional","affiliation":[{"name":"Science for Life Laboratory, Department of Protein Science, Division of Nanobiotechnology, KTH Royal Institute of Technology, 171 65 Solna, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.
