Research Group

The ultimate purpose of the “Materials for Chemical Analysis” (MAT4LL) Research Group of the University of La Laguna (http://mat4all.webs.ull.es/) is to design new, smart, sustainable, selective and efficient materials to be used in sample preparation methods for environmental, food and bioclinical analysis.

The group has adopted a multidisciplinary approach including not only analytical researchers but physics scientists and collaborations with organic chemists, inorganic chemists, material scientists and parasitologists. The current projects mainly deal with the synthesis of metal-organic frameworks, ionic liquids and derivatives, and polymers, their physicochemical characterization, their incorporation in microextraction and miniaturization strategies, together with the study of the interactions between the materials and the target analytes to improve the material designing step. In conclusion, our goal is the design of Materials For ALL.

Research Center

The MAT4LL group locates at the second floor of Chemistry building of the ULL, and it includes four labs, one of them with up to 6 gas chromatographs (3 with MS detection) and another one with up to 6 liquid chromatographs (1 with MS detection).

University Research Services

ULL includes an impressive facility full of advanced instrumentation and services within the Laboratories to support general Research (termed SEGAI), https://www.ull.es/servicios/segai/, with all techniques useful for characterizing materials and further analysis.

​​​​​​​Project research context

The current project of MAT4LL group is the GAROE^2 project (MAT2017-89207-R), involving the uses of advanced and smart materials as sorbents and solvents, with environmental-friendly features, for the development of valid strategies in water analysis. Particular emphasis on technology transfer is seek.

Document to be submitted

Applications should be submitted to Prof. Verónica Pino (veropino@ull.edu.es), including a CV, a motivation letter, and a concept note of the research proposal.
