DeepMind Watermarks AI-Generated Proteins

Google DeepMind launched SynthID Bio, a watermarking method that embeds detectable signatures into AI-designed proteins and predicted 3D structures while preserving biological function. In wet-lab tests on three targets, watermarked binders matched unwatermarked versions in hit rate and binding affinity. The tool aims to strengthen DNA synthesis screening and database integrity as AI-generated biological data grows.
