Proof of concept for watermarking AI-generated proteins while preserving biological function.

Today, we’re introducing SynthID Bio to bring watermarking technology to synthetic biology. SynthID Bio embeds an imperceptible signature directly into the biological code, ensuring the watermark is verifiable not just on a digital model but on the synthesized, physical protein itself – all while preserving its biological function in laboratory testing.

Generative AI is helping scientists address critical biological challenges, from predicting the structure of proteins ( AlphaFold ) to designing entirely new proteins ( AlphaProteo , and ProteinMPNN ), and more recently, developing new bacteriophages , viruses that infect bacteria.…
