The EU priority action lines state the need of advancing White Light-Emitting Diodes (WLED) replacing color filters with Inorganic Phosphors (IP: rare-earth elements and Cd quantum dot) for non-toxic and sustainable Organic Phosphors (OP).
ARTIBLED is inspired by highly efficient Bio-WLEDs based on Fluorescent Proteins (FPs), which are stable over weeks and beyond the state-of-the-art OP-WLEDs. However, the stability is limited by the intrinsic photodeactivation of FPs since natural chromophores were not matured by Nature to stand high photon flux excitations. Thus, there is an imperative need to enforce the evolution of photostable FPs directly prepared in bacteria. ARTIBLED proposes a radically new approach to prepare low-cost, highly efficient, and stable Bio-WLEDs by developing new biological synthesis tools to produce novel Artificial Fluorescent Proteins (AFPs) in bacteria, which will be achieved by combining tailored natural as well as de novo protein scaffolds with synthetic LED emitters (PLQY>50% with high photostabilities).
Thus, the novel Bio-WLEDs will also overcome previous limitations connected to photo-deactivation of natural chromophores. ARTIBLED aims to reach TRL4 for both AFP synthesis and Bio-WLEDs to fully meet the lighting needs at the forefront of the EU technology scenario by the end of the project.

The Technical University of Munich (TUM, project coordinator) has a unique profile with its core domains natural sciences, engineering, life sciences, and medicine. The institutional strategy is focused on strengthening the excellence of disciplinary core competences in research, teaching and learning, but is also targeted towards the promotion of ground-breaking and interdisciplinary research. TUM is committed towards the major challenges facing society in the 21st century in areas, such as energy, climate and environment, natural resources, health and nutrition, communication and information, mobility, and infrastructure. Besides research and teaching, TUM inspires and pro-actively empowers its 42,700 students, academics, and alumni to think and act entrepreneurially. TUM is regularly among the best national performers in international rankings.
In 2017, TUM founded the Integrative Research Center “Campus Straubing for Biotechnology and Sustainability (TUMCS)”, conducting fundamental research and technological developments on biogenic resources, biotechnology, and bioeconomy. Research focuses on chemical and energetic use of biogenic resources and its economic aspects. In 2020 the Biogenic Functional Materials Lab, headed by Prof. Rubén Costa, is created at TUMCS and will be involved in this project. The goal of his group is to progress technologies fulfilling the “green photonics” concept. His research portfolio spans from the designing of biogenic materials, stabilization methods in polymer matrices, and their use in energy related (lighting and photovoltaics) and medical (sensing and therapy) applications.
CIC biomaGUNE is a non-profit research organisation created in 2006 by the Basque Government to promote scientific research and technological
innovation related to biomaterials. The Centre comprises 12 international research teams conducting high-level research at the interface between chemistry, physics and biology, with particular emphasis on the properties and applications of molecular-level biological nanostructures. CIC biomaGUNE main research lines lie within the design, preparation and characterization of biofunctional nanostructures and their applications.
The Biomolecular Nanotechnology group (created in 2016) is the unit involved from CIC biomaGUNE. This group is led by Dr. Aitziber L. Cortajarena and
focuses on protein engineering toward the generation of functional nanostructures and bioinspired materials for applications in nanotechnology and nanomedicine. In detail, the group current research encompasses four main lines: i) proteins to template nanomaterials, ii) engineered proteins for biomolecular electronics, and iii) designed proteins to stabilized nanomaterials: imaging, sensing and catalysis iv) biofunctional structures for applications in nanomedicine. As such, they have a mature expertise going from the protein engineering, synthesis and characterization and the generation of protein-based hybrid structures and materials.
