Thus, the development of alternative approaches to remediate this environmental threat is urgently needed. Microrobots, combining autonomous motion with great tunability for the development of specific tasks, have turned into promising candidates to take on the challenge. Here, hybrid urchin\u2010like hematite (\u03b1\u2010Fe\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>3<\/jats:sub>\n                    ) microparticles carrying magnetite (Fe\n                    <jats:sub>3<\/jats:sub>\n                    O\n                    <jats:sub>4<\/jats:sub>\n                    ) nanoparticles and surface functionalization with organic \u03b2\u2010cyclodextrin (CD) molecules are prepared with the aim of on\u2010the\u2010fly encapsulation of illicit drugs into the linked CD cavities of moving microrobots. The resulting mag\u2010CD microrobots are tested against methamphetamine (MA), proving their ability for the removal of this psychoactive substance. A dramatically enhanced capture of MA from water with active magnetically powered microrobots when compared with static passive CD\u2010modified particles is demonstrated. This work shows the advantages of enhanced mass transfer provided by the externally controlled magnetic navigation in microrobots that together with the versatility of their design is an efficient strategy to clean polluted waters.\n                  <\/jats:p>","DOI":"10.1002\/smll.202306943","type":"journal-article","created":{"date-parts":[[2024,1,19]],"date-time":"2024-01-19T02:40:11Z","timestamp":1705632011000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Methamphetamine Removal from Aquatic Environments by Magnetic Microrobots with Cyclodextrin Chiral Recognition Elements"],"prefix":"10.1002","volume":"20","author":[{"given":"Paula","family":"Mayorga\u2013Burrezo","sequence":"first","affiliation":[{"name":"Future Energy and Innovation Laboratory Central European Institute of Technology Brno University of Technology  Purky\u0148ova 656\/123 Brno CZ\u2010616 00 Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmen C.","family":"Mayorga\u2013Martinez","sequence":"additional","affiliation":[{"name":"Center for Advanced Functional Nanorobots University of Chemistry and Technology Prague  Technick\u00e1 5 Prague 6 166 28 Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Kucha\u0159","sequence":"additional","affiliation":[{"name":"Forensic Laboratory of Biologically Active Substances Department of Chemistry of Natural Compounds University of Chemistry and Technology Prague  Technick\u00e1 5 Prague 6 166 28 Czech Republic"},{"name":"Department of Experimental Neurobiology National Institute of Mental Health  Topolov\u00e1 748 Klecany 250 67 Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5846-2951","authenticated-orcid":false,"given":"Martin","family":"Pumera","sequence":"additional","affiliation":[{"name":"Future Energy and Innovation Laboratory Central European Institute of Technology Brno University of Technology  Purky\u0148ova 656\/123 Brno CZ\u2010616 00 Czech Republic"},{"name":"Department of Medical Research China Medical University Hospital China Medical University  No. 91 Hsueh\u2010Shih Road Taichung 40402 Taiwan"},{"name":"Department of Paediatrics and Inherited Metabolic Disorders First Faculty of Medicine Charles University Prague  Ke Karlovu 2 Prague 128 08 Czech Republic"},{"name":"Advanced Nanorobots &amp;
