Ramon y Cajal researcher in the BEST research group at the University of Granada (Spain). Working on the synthesis os MOFs and their applications (now focused in water remediation and agriculture)

The people of the Biochemistry and Electronics as Sensing Technologies (BEST) group were participating in the European Researchers' night. In this experience showing the colors of chemistry to children from the city of Granada

These days we have participated in different conferences: Marisa M. Morales in the UKPorMat in Bristol José Zubeldia-Gutiérrez in the 3rd Symposium for Young Chemists in Rome Pablo Salcedo Abraira and Sara Rojas in the FrenchMOF A month full of meetings, contacts and novel opportunities!

I’m really excited and honored to be part of the "Water Safety Symposium (WWS) 2026" that will take place in Benasque Centro de Ciencias de Benasque Pedro Pascual. Abstract submission is still open (lnkd.in/dyK_3_sZ)! Can’t wait to be at WWS!

Great to visit with my research group the public school CEIP Fuentenueva (Granada) and perform some experiments with children aged between 4 and 8 years old. Also I organized the visit to the Department of Zoology and the "Classroom of te sea" in the University of Granada.

A little bit late to share but on 11th I was celebrating the International Day of Women and Girls in science with students from the CEIP VIRGEN DE FÁTIMA (Lancha del Genil in Granada). It's a pleasure to motivate children to choose STEM careers, and to realize that we are all capable of doing it.

Today we have the first presentation assay with our Palestine origin PhD student. I cannot image how far was the trip to arrive to this moment, but I am sure her defense will be great! Vamos!!

15/09/2025 It is a pleasure to welcome our new PhD students (Pablo Guerrero & Marisa Muñoz) to our group with some italian food. Further, Miriam Albán from @imdeaenergia.bsky.social will be with us for 2 months. With these enthusiastic students, we will soon have new exciting results!

A fantastic work driven by Samuel and Lourdes on the search of novel active structures. This time a Mg-based MOF as fertilizer agent, improving the activity of actually used agrochemicals pubs.acs.org/doi/10.1021/...

Controlled Magnesium Release and Nutritional Effect of a Novel Metal–Organic Framework on Plants

Fertilizer application is a necessary action in modern agriculture to meet the global food demand. Modern agriculture must enhance crop production while minimizing the amounts of used fertilizers to ensure environmental safety without compromising their effectiveness. One promising approach to achieve this ambitious goal is using controlled-release fertilizers, which provide an effective amount of active ingredients prolonged over time while reducing the losses caused by leaching into the soil. In this work, a novel metal–organic framework (MOF) [Mg2(C3H7O5P)2(H2O)4]·H2O, named GR-MOF-27, based on the antibacterial agent fosfomycin (FMC) and magnesium is reported. First, its crystal structure was determined by single-crystal X-ray diffraction, and then its stability in aqueous media was studied. The results showed a prolonged two-step release of Mg2+ ions (release rates of 26% in 4 h and 63% in 7 d), which fits to pseudo-first-order kinetic (first 4 h) and pseudo-second-order (from 4 h to 7 d) release models. Since the metal precursor (magnesium sulfate) is normally used as a fertilizer, the nutritional effects of GR-MOF-27 and MgSO4 were evaluated and compared, obtaining the result that GR-MOF-27 improves plant growth by increasing shoot, root, and dried weight by 10.5, 11.0, and 13.1%, respectively. Additionally, plants treated with GR-MOF-27 showed an increase in the uptake of important macronutrients, such as 64.9% of Mg and 57.4% of P, demonstrating the benefits of using MOFs as slow-release fertilizers.

Again in France, come back to my "other home". Thank you Thomas Devic for the invitation, it was fantastic to see you all, particularly people who worked in the Institute Lavoisier de Versailles, and share some science in the FrenchMOF 2025
