Coscientist

Autonomous chemical research system that generates liquid-handler control scripts and runs palladium-catalyzed cross-couplings, with its condition optimization run against previously collected, fully mapped yield datasets.

The loop

  1. Proposes

    An LLM planner designs reaction matrices and writes Opentrons Python protocol scripts and hardware commands.

  2. Judged by

    Protocol syntax checkers, robotic liquid handlers, and UV-vis plate readers execute the reactions and measure product yield.

  3. Steers

    The optimization study selects conditions against previously collected, fully mapped yield datasets.

Headline result

Autonomously executed Suzuki-Miyaura and Sonogashira cross-coupling reactions on cloud lab hardware and ran an optimization study that selected conditions against previously collected, fully mapped yield datasets.

What this does not prove

Wet-lab loop throughput is bounded by physical incubation and analytical characterization times.

How it generalizes the harness

Physical robotic reactors and spectrophotometric yield measurements judge the proposed experimental protocols.
