Designing new chemicals has long been a slow, expensive process, relying on repeated trial-and-error cycles of testing and optimization. Even with computer-assisted design, researchers face challenges in flexibility, efficiency, and ensuring that molecules can actually be synthesized in the real world.
Sciome is changing that. As part of the American Chemical Society (ACS) Fall 2025 Meeting, Dr. Ruchir Shah will present recent work highlighting development of a novel large language model (LLM) framework that generates new molecules in a modular, customizable way. Unlike traditional “one-size-fits-all” AI approaches, Sciome’s architecture allows researchers to swap in and out different domain specific modules depending on project needs, opening the door to faster, more targeted chemical-innovation.
To demonstrate the potential of this technology, Sciome applied its system to the urgent challenge of creating safer flame retardants (FRs). Flame retardants are widely used in everything from electronics to furniture, but many of the chemicals on the market today pose significant health and environmental risks. Using just 315 publicly available FR molecules as training data, Sciome’s system generated thousands of new molecular candidates. Most of these showed strong predicted fire-safety performance coupled with low toxicity—an unprecedented step toward safer alternatives.
The team further validated results with a custom-built predictive model, which confirmed high fire-retardant potential for many of the new molecules. Notably, the most promising candidates also scored highly on synthetic feasibility, meaning they could realistically be produced in the lab. Experimental combustion tests are now underway to confirm the results in practice.
With its modular, AI-driven platform, Sciome is demonstrating how cutting-edge machine learning can accelerate chemical design—paving the way not only for safer flame retardants, but for a wide range of molecular innovations in medicine, materials, and beyond.
The American Chemical Society Fall 2025 Meeting (ACS Fall 2025), being held in Washington, D.C. August 17-21, brings together thousands of chemistry professionals to meet and share ideas and advance scientific and technical knowledge.
