Irradiación gamma, Química verde, Caracterización de nanopartículas, Nanopartículas de selenioResumen
El selenio, un micronutriente esencial en pequeñas cantidades, presenta numerosos efectos beneficiosos en organismos como humanos, plantas y bacterias. Sin embargo, la relación entre el selenio y los organismos vivos es compleja debido a su estrecho rango de acción, que puede variar de beneficioso a perjudicial dependiendo de la concentración. Las nanopartículas de selenio (SeNPs) muestran un gran potencial debido a su reconocida biocompatibilidad, biodisponibilidad y baja toxicidad. No obstante, antes de considerar cualquier aplicación potencial, los parámetros fisicoquímicos de las SeNPs — como tamaño, forma, composición, estado de agregación y carga superficial — deben caracterizarse cuidadosamente, ya que la metodología de síntesis puede influir en su toxicidad. En el presente estudio utilizamos un método radiolítico, empleando radiación de ⁶⁰Co, para sintetizar SeNPs y posteriormente evaluamos detalladamente sus parámetros fisicoquímicos.
