Grupo de Macromoléculas Organometálicas Electroactivas (GMOE)


Research lines

The main objective of our research is the design and synthesis of new redox active organometallic macromolecules (dendritic or polymeric). In particular, the following lines of research are carried out:

1.-Design, synthesis and characterization of dendritic fragments (dendrons) functionalized with electroactive metallocenes. 

2.-Synthesis of dendritic macromolecular structures with different metallocenes.

3.-Study of the electrochemical properties of the organometallic macromolecules both in solution and immobilized on electrode surfaces.

4.-Development of electrode surfaces with dendritic macromolecules as templates to prepare size-controlled metallic nanoparticles (Pt, Au, or alloys Au-Pt).

5.-Development of electrochemical biosensors using both, surfaces with size- controlled nanoparticles prepared from dendrimers as templates, or macromolecules deposited onto the electrode surface or onto metallic nanoparticles.

6.-Development of electrochemical sensors based on organometallic macromolecules for the molecular recognition of ions and neutral molecules.
