The ICN2 organaized the 1st Severo Ochoa on Environment, focused on Environmental Monitoring and Remediation

On the 16-17th of December, the Catalan Institute of Nanoscience and Nanotechnology organized the First Severo Ochoa Workshop on Environment, at the Casa de Convalescència (Barcelona). This workshop on Environmental Monitoring and Remediation aimed to bring together leading academic scientists, researchers, scholars and industry representatives to exchange and share their experiences and results on all the aspects involved in pollutant detection, monitoring, scavenging and degradation. The workshop topics also covered the life-cycle of nanomaterials as potential pollutants and their impact on the ecosystem. This event was organized by Dr. Neus Bastús (CSIC Tenured Scientist), Dr. Maria José Esplandiu (CSIC Scientific Researcher) and Jessica Casandra Ramírez (Doctoral Student).

Dr. Salvio Suárez-García was one of the speakers with his talk entitled “Sustainable approaches for environmental challenges“.

He showed the developed technologies by our Group, facing three of the main key challenges in environmental remediation: i) removal of microplastics, ii) capture and inactivation of pathogens (viruses and bacteria) and iii) entrapment of particles, chemical contaminants and other pollutants. To address these challenges, we have developed two different sustainable approaches. The first one, developed by Dr. Claudio Roscini, consists of the formation of capsules through coacervation processes and biodegradable polyelectrolytes that entrap almost any kind of micro/nanomaterials. The weight of the resulting composite induces its sedimentation, thus facilitating their efficient separation. As a proof-of-concept, this technology has been validated by entrapping NPs of different i) type (organic, inorganic, solid or oil nanodroplets, ii) dimension (10-600 nm) and iii) surface charge (positive or negative), both in simulated and real laboratory waste environments. The second technology develops mussel-inspired polymeric coatings for water and air filters to enhance their remediation capacities, such as wettability (hydrophobic/hydrophilic), oil absorption, roughness, and the ability to entrap different types of particles and pathogens. The composition and thickness of the designed coatings, which are effective over a broad range of surfaces (metals, fabrics, polymers, paper and filters), can be fine-tuned and subsequently functionalized with other (bio)molecules of interest (e.g., biocide moieties).

Technologies for environment remediation: a) complex coacervation and b) formation of bioinspired universal coatings.

This workshop allowed for the opportunity to present and discuss the most recent innovations, trends, and concerns in the field, the practical challenges encountered, and the solutions adopted. Furthermore, as discussed during the event, the industrial vision will be of great value to bring focus to the academic research lines.
