Estado del arte sobre nanopartículas bimetálicas con estructura núcleo-coraza: clasificación, propiedades, síntesis, caracterización y aplicaciones State of the art on bimetallic nanoparticles with core-shell structure: classification, properties, synthesis, characterization and applications

En las ultimas decadas, ha existido un creciente interes por la fabricacion, sintesis y preparacion de nanoparticulas bimetalicas (compuestas por dos elementos metalicos diferentes). Al combinar dos metales en estos nanomateriales, su desempeno mu¬chas veces supera las propiedades asociadas con sus contrapartes monome¬talicas, y cambiando sus componentes y morfologias se puede modificar exitosamente su desem¬peno fisico, electrico o quimico. Ampliando de esta manera su campo de aplicacion a areas tales como administracion de farmacos, optica-electronica, biosensores, separacion quimica, materiales, biotecnologia, nanoactuadores, bioimagen y bioterapia. La versatilidad de poder entender como combinar distintos elementos metalicos, en diferentes proporciones, a nivel nanometrico y de forma controlada, constituye un nuevo paradigma en la ingenieria de nanomateriales. In recent decades, there has been a growing interest in the manufacture, synthesis and preparation of bimetallic nanoparticles (composed of two different metallic elements). By combining two metals in these nanomaterials, their performance often exceeds the properties associated with their monometallic counterparts, and changing their components and morphologies can successfully modify their physical, electrical or chemical performance. Expanding in this way its field of application to areas such as drug administration, optics-electronics, biosensors, chemical separation, materials, biotechnology, nano-actuators, bioimaging and biotherapy. The versatility of being able to understand how to combine different metallic elements, in different proportions, at a nanometric level and in a controlled manner, constitutes a new paradigm in the engineering of nanomaterials.
