She joined Prof. Paulino Tuñón Blanco's group in 2004 to pursuit graduate student within the research line focused on the synthesis, characterization, evaluation and application of molecularly imprinted polymers (MIPs). Specifically, he work is devoted to the development of "artificial enzymes", a novel application of MIPs. These polymers exhibit a high affinity for a target molecule and catalyze some reaction involving that molecule.
She is mimicking the activity of chloroperoxidase enzyme, which is tradicionally used in catalytic halogenations and whose ability to catalyze the dehalogenation of halophenols has recently been developed. 2,4,6-trichlorophenol is one of the 11 environmental pollutants established by EPA and this enzyme is capable of convert them into the corresponding dichloroquinone. The acrylic MIP developed has protoporphyrin IX or Hemin as active center and its synthesis is carried out according to DFT calculations previously done in our lab. The catalytic reaction is being studied by means of voltammetric techniques and HPLC.
She is was awarded a FPI grant associated to the project DGICYT CTQ2005-01376/BQU. "Molecular computational design of artificial enzymes and affinity receptors based on molecularly imprinted polymers: Biomimetic electrochemical sensors"
Currently she is a postdoctoral researcher at Prof. Ramón Barrio Laboratory at Universidad del País Vasco.
