Con un tama\u00f1o de una millon\u00e9sima de mil\u00edmetro, los nanodiamantes pueden recubrirse con medicamentos y enviarse al tejido corporal a trav\u00e9s de la piel sin causar da\u00f1o.<\/span><\/em><\/strong><\/p>\n

Por Abigail Klein Leichman, <\/span>Israel21c<\/span><\/a><\/em><\/p>\n

La piel es uno de los \u00f3rganos m\u00e1s grandes y accesibles del cuerpo humano, pero penetrar sus capas profundas para tratamientos m\u00e9dicos y cosm\u00e9ticos ha resultado ser un desaf\u00edo.<\/span><\/p>\n

Investigadores de la Universidad Bar-Ilan (BIU) en Israel est\u00e1n enfrentando ese desaf\u00edo con part\u00edculas nanom\u00e9tricas de diamante lo suficientemente peque\u00f1as como para administrar dichos remedios de manera segura a trav\u00e9s de la epidermis, la dermis y las capas de grasa de la piel.<\/span><\/p>\n

Tambi\u00e9n crearon un m\u00e9todo \u00f3ptico no invasivo basado en l\u00e1ser que cuantifica la penetraci\u00f3n de nanodiamantes y determina su ubicaci\u00f3n y concentraci\u00f3n dentro del tejido corporal, eliminando la necesidad de una biopsia.<\/span><\/p>\n

\u201cEste es un avance significativo en dermatolog\u00eda y en ingenier\u00eda \u00f3ptica\u201d, dijo el Prof. Dror Fixler, director del Instituto de Nanotecnolog\u00eda y Materiales Avanzados de BIU y miembro del equipo de investigaci\u00f3n.<\/span><\/p>\n

\u201cPodr\u00eda abrir la puerta al desarrollo de medicamentos aplicados a trav\u00e9s de la piel junto con preparaciones cosm\u00e9ticas modernas que utilizan nanotecnolog\u00eda avanzada\u201d.<\/span><\/p>\n

La investigaci\u00f3n de Fixler, asistida por la investigadora Channa Shapira y otros, se public\u00f3 en la revista cient\u00edfica ACS Nano.<\/span><\/p>\n

Los nanodiamantes, de un tama\u00f1o de una millon\u00e9sima de mil\u00edmetro, se producen al detonar explosivos dentro de una c\u00e1mara cerrada. En estas condiciones, la alta temperatura y la presi\u00f3n hacen que los \u00e1tomos de carbono que se encuentran en los explosivos se fusionen. Los nanodiamantes creados en el proceso son lo suficientemente peque\u00f1os para penetrar en el tejido, e incluso en las c\u00e9lulas, sin causar da\u00f1o.<\/span><\/p>\n

Miembros de la Facultad de Ingenier\u00eda y del Departamento de Qu\u00edmica de Kofkin de BIU participaron en el proyecto.<\/span><\/p>\n
