15 May: TRANSLOCATION OF ENZYMES INSIDE MOFS FOR ENHANCED ACTIVITY UNDER EXTREME CONDITIONS

On a recently published joint work, Jose, Neyvis and Belén used a novel method to induce the translocation of an enzyme into the pores of a MOF. Their procedure is based in a partial denaturation of the enzyme followed by its refolding into the polar cavities offered by the host. Thanks to a combination of experimental and theoretical work, we managed to demonstrate that the enzyme adopts a different conformation inside the MOF, granting it enhanced activity, stability and recyclability. The work is now available in Chemical Science

10 Ene: ORIGIN OF THE CHEMIRESISTIVE RESPONSE OF ULTRATHIN FILMS OF CONDUCTIVE METAL–ORGANIC FRAMEWORKS

Víctor, Neyvis and Garin’s work has just been published in Angewandte Chemie Int. Ed. This joint effort shines some light into the underlying mechanism behind the chemiresistive phenomena displayed by electrically conductive MOFs. Taking advantage of our previously reported devices based on Cu-CAT-1 ultrathin films (~30 nm), we used experimental data in combination with computational modelling to obtain evidence for a guest dependent modification of the MOF’s electronic structure. This causes a direct dependence between the electrical response of the MOF and guest interactions with its open metal nodes. You can see the full text here
