The Nanoparticles and Nanocomposites (NN) Group is an interdisciplinary group with diverse research interests but with a focus on the rational synthesis of nanoparticles, nanocelluloses, and nanocomposites and the study of their structural-functional properties including those related to the nano/bio-interfaces. Current activities are:
The group vision is to advance in the knowledge of application-oriented nanomaterials in the fields of Nanomedicine, Information Technologies, or Energy and Environment. The NN members participate actively in science outreach and gender equality initiatives.
Most of the NN research highlights published during 2019 spin around the development of application-oriented nanocellulose-based materials. Because cellulose is a non-toxic, degradable, and almost inexhaustible biopolymer it is expected to play a strategic role in replacing petroleum-based polymers and in advancing towards a circular economy. Nanocelluloses combine the properties of cellulose with the high surface area of nanomaterials. Increasing demand for cost-effective, sustainable, and high-performance materials makes nanocelluloses attractive for innovative applications in many sectors such as food packaging, flexible electronics, sensors, or biomaterials. In particular, bacterial nanocellulose (BC) produced by microbial fermentation has the same molecular formula as plant-derived cellulose but with a higher degree of polymerization, purity and crystallinity.
The group, in collaboration with several labs in Europe, exploits BC exceptional features to create advanced functional materials. The figure below illustrates some relevant developments from this period. Briefly, i) fabrication of a multinanoparticle millefeuille as a BC layered construct, ii) demonstration of the use of BC/carbon nanotubes as a sustainable thermoelectric device and as a novel component for solar energy harvesting, iii) validation of the antimicrobial and antifungal properties of BC/Ag nanocomposite in plant foliage and iv) reviewing the opportunities of BC to treat epithelial tissues, with specific focus being its use as a corneal bandage.
Importantly, three new projects started in 2019 which will also give an impetus to other activities of the group. An ERC-Consolidator grant (M. Gich) aimed at identifying new materials and components for the 5G-communications scenario, a Ramon Areces funded project “Synthetic nanoparticles as an innovative treatment for sepsis” and a RETOS project to continue the work on cellulose-based materials “Rising the impact of Selected Engineered Bacterial Cellulose Composites”.
