Espectroscopía vibracional sobre nanoestructuras metálicas (SERS y SEIR): nuevos sustratos y aplicaciones

Abstract

[ES] El trabajo presentado constituye un resumen de la labor investigadora llevada a cabo en nuestro grupo, en el Instituto de Estructura de la Materia sobre las líneas de investigación siguientes: a) Preparación de superficies metálicas nanoestructuradas con aplicaciones en espectroscopías vibracionales intensificadas por nanoestructuras, fundamentalmente SERS y SEIR; b) Caracterización de dichas superficies por métodos espectroscópicos y microscópicos; c) Funcionalización de las nanoestructuras obtenidas mediante moléculas altamente específicas capaces de autoensamblaje; y, finalmente, d) aplicación de dichas superficies (metal-receptor) al estudio y detección de ligandos de interés medioambiental y/o biológico. Se presentan algunos ejemplos de estas aplicaciones, en concreto, la detección de PAHs (hidrocarburos policíclicos aromáticos) mediante calixarenos y el estudio de la interacción del fármaco emodina con albúmina de suero humana.

[EN] This work summarises the researching activity carried out in our group, placed in the Institute of the Matter Structure, on the following researching lines: a) Preparation of nanostructured metallic surfaces with potential applications in nanostructure-enhanced vibrational spectroscopy, mainly SERS and SEIR; b) Characterisation of the above surfaces by spectroscopic and microscopic methods; c) Functionalisation of such nanostructured surfaces by highly specific molecules able to be self-assembled on the surface; and, finally, d) application of these surfaces (metal-host) to the study and detection of ligands with environmental and/or biological interest. In this work, examples of these applications are shown for the case of the detection of PAHs (Polycyclic Aromatic Hydrocarbons) by means of calixarene host molecules, and the interaction study of emodin drug with human serum albumin.
