Un material que sacude físicamente las capas de bacterias abre una alternativa a depender solo de medicamentos. Para un paciente que tiene una prótesis o un marcapasos, eso podría significar menos cirugías y menos complicaciones. Todavía se probó en ratones, y falta mucho para que llegue a un consultorio.","quienFirma":"Universidad de Michigan","confianza":"revisado","consulta":null},"sello":{"hash":"b0ec656dd633d7db7c990c68910bd6a6410bbde94494c35d8a1525770ccb79dd","sello":"78aa4461c67efa33ccf6a9b234829005f38db37eb1a2208e4776b5608c2b3266","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6589214,"aleatorio":"52b9f603f2adb401be50f1c992d4298d190e6490609299f99607e3b0c12251b3","tiempo":"2026-10-27T13:24:00.000Z"},"nist":{"cadena":2,"pulso":2001772,"salida":"0E703280D2ECB99CF237148891BE4B05125CA4A9FA93BA99C93DE108693398FC1C1436A917C2E942D3FD99D4FACCDDC40E70589522F4EEDE9B18514294B0BD55","tiempo":"2026-10-27T12:55:00.000Z"},"noAntes":"2026-10-27T13:24:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 27 13:24:17 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Nano-wrinkles and actuation break up infectious biofilms on implants","descripcion":"A nano-wrinkled surface combined with a tiny soft actuator can break up infection-causing bacterial sheets, called biofilms, that form on medical implants, according to a University of Michigan Engineering study published in Advanced Functional Materials. When implanted in mice, the platform—called DARTS (dynamically actuated reconfigurable topographical surface)—reduced bacterial burden and improved the surrounding tissue response.","pubDate":"Tue, 27 Oct 2026 09:20:01 EDT","url":"https://phys.org/news/2026-10-nano-wrinkles-actuation-infectious-biofilms.html"},"indexado":"2026-10-27T13:23:51.476Z"}}
