Los Angeles2 undergraduates at the University of California, Los Angeles built an electroporation rig running 384 wells unattended.
The system automates 96- and 384-well plate workflows, cutting cell transfection from hours to minutes.
It targets the last manual step in synthetic-biology gene delivery.

THE MECHANISM
Electroporation pulses cells with a high-voltage electric field (typically 1-2 kV/cm) for microseconds, transiently opening nanometer-scale pores in the lipid bilayer. DNA, RNA, or proteins diffuse through before the membrane reseals.
WHY IT'S THE BOTTLENECK
Liquid handling, PCR, sequencing, and colony picking have all been automated for decades. Electroporation stayed manual because each well needs a cuvette swap, an electrode wash, and a pulse — a workflow that resisted standardization until microplate-format electrodes matured.
THE 96 vs 384 JUMP
A 384-well plate has the same footprint as a 96-well plate but four times the density (4.5mm well spacing instead of 9mm). Going from 96 to 384 quadruples throughput without quadrupling reagent cost — the volumes drop from ~100μL to ~25μL per well.
THE SDL CONCEPT
A self-driving lab (SDL) closes the loop: a robot runs the experiment, an algorithm reads the result, and the next experiment is designed without a human in the loop. The bottleneck is whichever step still needs hands — which is why automating the last manual step is disproportionately valuable.
WHY UNDERGRADS
Synthetic biology hardware has followed the same trajectory as personal computing: components that cost $100K in a pharma lab now exist as $500 open-source kits. The barrier to building a transfection rig is no longer capital — it is the engineering taste to know which step actually matters.
