Un laboratorio del Technion de Israel creó un apósito inteligente que tiene la capacidad de curar heridas sin suturas.

Durante mucho tiempo, un elemento básico de la ciencia ficción fue burlarse de la suturas simples de heridas haciéndolas ver obsoletas. Y es que la técnica de cierre de lesiones se usa desde hace unos 5.000 años.

El laboratorio de ingeniería química del profesor Hossam Haick en el Instituto de Tecnología Technion de Israel patentó una solución que consiste en la creación de un apósito inteligente: une los bordes de una incisión quirúrgica, administra medicamentos, la protege de infecciones e informa sobre el progreso de la lesión.

Además, el apósito se aplica en la zona antes de realizar una incisión quirúrgica. Tras la intervención, ambos extremos de la herida se unen en apenas tres segundos.

La solución puede liberar antibióticos para ayudar a prevenir infecciones y se conecta de forma inalámbrica a los dispositivos inteligentes del equipo médico. Así, puede generar informes en tiempo real sobre cambios de temperatura, pH y niveles de glucosa.

Haick indicó que la idea se le ocurrió una noche luego de ver una película sobre robótica futurista con sus hijos. “Allí pensé, ¿y si realmente pudiéramos hacer sensores autorreparables?”, recordó.

Al día siguiente se puso a trabajar en la idea pero había un problema: el sensor no era biocompatible. Es decir, no se podía utilizar en contacto con la piel y la sangre.

Ning Tang, un estudiante postdoctoral de Haick, trabajó en el desarrollo de un polímero tanto biocompatible como autocurativo.

Se trata de una cremallera molecular hecha de azufre y nitrógeno. El bisturí del cirujano lo abre, luego, cuando se presiona, se cierra y se mantiene firme. Los nanotubos de carbono integrados proporcionan conductividad eléctrica e integran la matriz de sensores.

En pruebas de laboratorio, las heridas que se cerraron con el apósito inteligente sanaron tan rápido como las que se suturaron de forma tradicional. Además, mostraron tasas de infección bien reducidas.

“Usamos os avances de la cuarta revolución industrial: dispositivos inteligentes interconectados. Es un nuevo enfoque para el tratamiento de heridas”, definió Haick, que informó que la tecnología ahora está patentada y que su equipo inició conversaciones con algunas agencias para llevar esta tecnología al mercado.
