A team of ingenious bioengineers at Arizona State University (ASU) has harnessed the power of childhood nostalgia, unveiling a creative solution to a long-standing challenge in DNA origami research.

They’ve successfully employed a LEGO robotics kit to build an affordable, highly effective gradient mixer for purifying self-assembling DNA origami nanostructures. This innovative breakthrough, detailed in a paper published one PLOS ONE, promises to revolutionize how scientists approach DNA origami synthesis.

The creation of DNA origami structures is an intricate process, requiring precise purification of nanostructures. Traditionally, this purification step involved rate-zone centrifugation, relying on a costly piece of equipment called a gradient mixer. However, the maverick minds at ASU have demonstrated that even the iconic plastic bricks of LEGO can be repurposed for scientific advancement.
