This innovation, among others, is based on using a capacitator bank that dynamically adjusts the frequency. To validate the novel system, a series of experiments were conducted using commercial magnetic nanoparticles (MNPs) demonstrating the device\u2019s effectiveness and allowing us to identify new challenges associated with the design of more powerful devices. A computational model was also used to validate the device and to allow us to determine the best system configuration. The results obtained are consistent with those from other studies using the same MNPs but with magnetic hyperthermia commercial equipment, confirming the good performance of the developed device (e.g., consistent SAR values between 1.37 and 10.80 W\/gMNP were obtained, and experiments reaching temperatures above 43 \u00b0C were also obtained). This equipment offers additional advantages, including being economical, user-friendly, and portable.<\/jats:p>","DOI":"10.3390\/nano14221848","type":"journal-article","created":{"date-parts":[[2024,11,19]],"date-time":"2024-11-19T11:58:07Z","timestamp":1732017487000},"page":"1848","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Portable Homemade Magnetic Hyperthermia Apparatus: Preliminary Results"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4359-0082","authenticated-orcid":false,"given":"Teresa","family":"Castelo-Grande","sequence":"first","affiliation":[{"name":"LEPABE\u2014Laboratory for Process Engineering, Environment, Biotechnology and Energy, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"},{"name":"AliCE\u2014Associate Laboratory in Chemical Engineering, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3332-4226","authenticated-orcid":false,"given":"Paulo A.","family":"Augusto","sequence":"additional","affiliation":[{"name":"Institute of Molecular and Cellular Biology of Cancer, CSIC\/University of Salamanca (GIR Cit\u00f3mica), 37007 Salamanca, Spain"},{"name":"CEADIR\u2014Center for Environmental Studies and Rural Revitalization, Avenida Filiberto Villalobos, 119, 37007 Salamanca, Spain"}]},{"given":"Lobinho","family":"Gomes","sequence":"additional","affiliation":[{"name":"Faculty of Natural Sciences, Engineering and Technologies, Lus\u00f3fona University of Porto, R. de Augusto Rosa 24, 4000-098 Porto, Portugal"}]},{"given":"Eduardo","family":"Calvo","sequence":"additional","affiliation":[{"name":"CEFT\u2014Center of Study of Phenomena\u2019s of Transport, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6707-9775","authenticated-orcid":false,"given":"Domingos","family":"Barbosa","sequence":"additional","affiliation":[{"name":"LEPABE\u2014Laboratory for Process Engineering, Environment, Biotechnology and Energy, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"},{"name":"AliCE\u2014Associate Laboratory in Chemical Engineering, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, 4200-465 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1316","DOI":"10.1080\/02656736.2018.1430867","article-title":"Magnetic hyperthermia therapy for the treatment of glioblastoma: A review of the therapy\u2019s history, efficacy and application in humans","volume":"34","author":"Mahmoudi","year":"2018","journal-title":"Int.
