New fluorescent proteins and bio-matrices for eco-friendly illumination systems
White inorganic light-emitting diodes (WLEDs) provide excellent efficiency and stability but rely on rare earth chemical elements. Bio-hybrid WLEDs (Bio-WHLEDs) represent a sustainable and cost-effective alternative using fluorescent proteins (FPs) embedded into a synthetic polymer matrix. Currently, Bio-WHLEDs are limited to low-power applications as the continued excitation of FPs leads to denaturation. The EU-funded NMPLED project aims to design and develop improved matrices and proteins for the new generation of all bio-based colour down-converting coatings. Researchers propose to encapsulate the FPs into natural source biopolymers-based packaging matrices and replace the GFP-based proteins with a new class of dedicated FPs to increase the overall photostability of the FPs.
