Aspuru-Guzik team demos a lab that builds itself from scratch

A laboratory that builds itself. Alán Aspuru-Guzik's group at Toronto has posted a preprint on what they call "self-building laboratories": systems that, given a high-level scientific goal, assemble their own lab layout, digital twin, robot skills and experimental workflows.

"Existing SDL can only run the procedures they were built for," the authors write. "Adapting them to a new experiment still requires extensive manual engineering, which makes laboratory flexibility the bottleneck for scaling discovery."

To validate the setup they ran a water-soluble cadmium sulfide quantum-dot synthesis. The system orchestrated 236 OT-2 liquid-handling commands onto a 96-well plate, then moved it through 19 robotic stages involving an xArm5 manipulator with a 6-axis force/torque sensor, an Agilent PlateLoc sealer and a BioTek Cytation5 multimode reader. Reaction pH 8.5–10.0. Cd:MPA molar ratios from 1:0 to 1:2. 8 hours at 60°C. The paper reports "the optimal ligand loading of 0.75–1.5 equivalents," with preferred quantum-dot formation at elevated pH values.

By "shifting human researchers from manually configuring and programming device automation to specifying scientific objectives," SBL makes scientific automation "more accessible, flexible, and scalable," the authors argue.

One chemistry, one plate. The abstract claims SBL scales "from a single workstation to laboratories with several robots working together," but publishes only the single end-to-end CdS run as validation.
