The selection of continuous phase included hydrocarbon, fluorinated, and silicone oils. To map the acoustic properties of the oils, we measured their speed of sound and density. We then studied the acoustic performance of each oil for droplet-internal manipulation through experiments and finite-element simulations (COMSOL Multiphysics\u00ae, COMSOL, Stockholm, Sweden). From our results, we conclude that a match between the speed of sound of the continuous and dispersed phases is strongly correlated to the generation of a strong and uniform acoustic field inside the droplet. We demonstrate that conventionally favoured fluorinated oils in droplet microfluidics are no longer the best choice when considering droplet-internal acoustic focusing. Instead, hydrocarbon oils, especially linseed oil, are most suitable for this specific application as they generate stable and monodisperse droplets and bear the most resemblance to water in terms of acoustic properties. We believe this collection of data will serve the acoustofluidics community by providing results that aid in the selection of continuous phase in future droplet acoustofluidic studies and data for performing acoustofluidic simulations.", "doi": "10.1121/10.0036771", "pmid": "40478185", "labels": [], "xrefs": [{"db": "pii", "key": "3349134"}], "notes": [], "created": "2026-08-20T11:19:32.964Z", "modified": "2026-08-20T11:19:33.235Z"}, {"entity": "publication", "iuid": "91405623b285409eabccccde8100a0bc", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/91405623b285409eabccccde8100a0bc.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/91405623b285409eabccccde8100a0bc"}}, "title": "Integration of multiple flexible electrodes for real-time detection of barrier formation with spatial resolution in a gut-on-chip system.", "authors": [{"family": "Lucchetti", "given": "Mara", "initials": "M", "orcid": "0000-0002-3057-983X", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/a64adffc16d94185884350098ebb11dd.json"}}, {"family": "Werr", "given": "Gabriel", "initials": "G", "orcid": "0000-0001-9503-5481", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/90e0ce9e278f4c44b8125dd84758f573.json"}}, {"family": "Johansson", "given": "Sofia", "initials": "S", "orcid": "0000-0003-3672-9883", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/d976bdc17d7248d6b60c4f7a47fc84c7.json"}}, {"family": "Barbe", "given": "Laurent", "initials": "L", "orcid": "0000-0003-4475-6478", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/f9b28e1a0e95432881ff25ae35da88d4.json"}}, {"family": "Grandmougin", "given": "L\u00e9a", "initials": "L"}, {"family": "Wilmes", "given": "Paul", "initials": "P", "orcid": "0000-0002-6478-2924", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/e169727cc0f9482baf98944388a77b24.json"}}, {"family": "Tenje", "given": "Maria", "initials": "M", "orcid": "0000-0002-1264-1337", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/bd13273274574923b354ca9c605efc8f.json"}}], "type": "journal article", "published": "2024-01-24", "journal": {"title": "Microsyst.

To study the effect of probiotics, dietary compounds and drugs on gut barrier formation and disruption, human gut epithelial and bacterial cells can be cocultured in an in vitro model called the human microbial crosstalk (HuMiX) gut-on-a-chip system. Here, we present the design, fabrication and integration of thin-film electrodes into the HuMiX platform to measure transepithelial electrical resistance (TEER) as a direct readout on barrier tightness in real-time. As various aspects of the HuMiX platform have already been set in their design, such as multiple compressible layers, uneven surfaces and nontransparent materials, a novel fabrication method was developed whereby thin-film metal electrodes were first deposited on flexible substrates and sequentially integrated with the HuMiX system via a transfer-tape approach. Moreover, to measure localized TEER along the cell culture chamber, we integrated multiple electrodes that were connected to an impedance analyzer via a multiplexer. We further developed a dynamic normalization method because the active measurement area depends on the measured TEER levels. The fabrication process and system setup can be applicable to other barrier-on-chip systems. As a proof-of-concept, we measured the barrier formation of a cancerous Caco-2 cell line in real-time, which was mapped at four spatially separated positions along the HuMiX culture area.", "doi": "10.1038/s41378-023-00640-x", "pmid": "38268774", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC10805851"}, {"db": "pii", "key": "640"}], "notes": [], "created": "2026-08-20T08:48:03.488Z", "modified": "2026-08-20T08:48:03.647Z"}, {"entity": "publication", "iuid": "8d016b58a2704e13a9c73ed08efcc8af", "links": {"self": {"href": "https://publications-affiliated.scilifelab.se/publication/8d016b58a2704e13a9c73ed08efcc8af.json"}, "display": {"href": "https://publications-affiliated.scilifelab.se/publication/8d016b58a2704e13a9c73ed08efcc8af"}}, "title": "Integrated thin film resistive sensors for in situ temperature measurements in an acoustic trap", "authors": [{"family": "Werr", "given": "Gabriel", "initials": "G", "orcid": "0000-0001-9503-5481", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/90e0ce9e278f4c44b8125dd84758f573.json"}}, {"family": "Khaji", "given": "Zahra", "initials": "Z", "orcid": "0000-0002-5452-7831", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/8d104770c8514983917f0096243c5ba9.json"}}, {"family": "Ohlin", "given": "Mathias", "initials": "M"}, {"family": "Andersson", "given": "Martin", "initials": "M"}, {"family": "Klintberg", "given": "Lena", "initials": "L"}, {"family": "Searle", "given": "Sean S", "initials": "SS"}, {"family": "Hjort", "given": "Klas", "initials": "K"}, {"family": "Tenje", "given": "Maria", "initials": "M", "orcid": "0000-0002-1264-1337", "researcher": {"href": "https://publications-affiliated.scilifelab.se/researcher/bd13273274574923b354ca9c605efc8f.json"}}], "type": "journal-article", "published": "2019-09-01", "journal": {"title": "J.
