Project description
New white LED technology with luminescent proteins
White light-emitting diodes (LEDs) are the next big thing in lighting. They are now being used in a wide range of lighting applications from indoor to road lighting such as streetlights, flashlights, and vehicle headlights. Nevertheless, they still have room for improvement, as current manufacturing processes are either very expensive or based on unsustainable inorganic metals. The EU-funded ARTIBLED project will introduce a new, rather unusual manufacturing method to produce low-cost and highly efficient LEDs: using artificial fluorescent proteins. Scientists are planning to synthesise these proteins in bacteria by combining tailored natural and de novo protein scaffolds with synthetic LED emitters. Project achievements will keep Europe at the forefront of innovation in lighting.
Objective
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). ENABLED 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. ENABLED 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. ENABLED 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.
