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.
