Nanotecnología

LABORATORIO DE MATERIA BLANDA

   Films Macromoleculares Funcionales: Los objetivos se centrarán en extender el uso de bloques de construcción “blandos” al diseño de superficies multifuncionales con propiedades químicas y físicas bien definidas.

  Ensamblado Dirigido por Reconocimiento Molecular: Las investigaciones se enfocarán en la búsqueda de nuevas rutas para el diseño de materiales funcionales basados en ensamblados biosupramoleculares de glicoproteínas.

  Estructuras Macromoleculares Nanoconfinadas: Se buscarán nuevas rutas para manipular y controlar el transporte de especies químicas a través de entornos nanoconfinados mediante el uso de arquitecturas poliméricas “activas” ó “inteligentes”.

  Construcción de Nanomateriales Supramacromoleculares: Se investigará el uso de bloques macromoleculares, tales como micelas unimoleculares ó copolímeros en bloque, para construir arreglos superestructurales “blandos” con funcionalidades específicas.
