GEAS Research Lines
Our lines of research
,The research lines of the GEAS group correspond to the following three lines of work:
I. Analytical Nanometrology.
The research, development and application of new techniques, methods and analytical platforms for the detection, characterization, and quantification of both synthetic and natural nanomaterials in consumer products, the environment and biological systems, and individual particle and cell detection techniques.
II. (Bio) Electrochemical and optical analytical sensors.
The design, development, and application of catalytic (enzymes) and affinity (antibodies, aptamers) (bio)sensors for the determination in situ of contaminants, clinical parameters, and other parameters of interest in the field of environment, food safety, and biochemistry clinics.
III. Characterization of heritage materials.
Non-destructive instrumental techniques for the best knowledge and preservation of the artistic and historical heritage, with special emphasis on the study of ceramics, pigments and organic wastes.
