As of now the research is inconclusive, but optimistic. Lawsone non-specifically targets primary amino acids, and displays photoluminescence with forensic light sources. It has a characteristic purple/brown coloration as opposed to the purple/blue associated with ninhydrin.
Currently, the research is yielding ambiguous yet promising outcomes. Lawsone generally targets primary amino acids and displays fluorescence under specific light conditions. It has a unique purple/brown appearance that differs from the purple/blue coloration seen with ninhydrin.
