We report the unprecedented synthesis of gold nanoclusters using green fluorescent protein (GFP)-expressing bacteria as the stabilizer. Combining the blue and green fluorescence of GFP-expressing bacteria and orange luminescence of the nanoclusters, white light emission associated with appreciable quantum yield, color rendering index and correlated color temperature was achieved. Decorating bacterial surface with gold nanoclusters for white light emission.
