“How a Children’s Toy Could Help Fight Malaria”%0D%0Aby Jason Daley%0D%0A%0D%0AOne of the most basic and necessary pieces of equipment in a medical lab is a centrifuge. Often bulky and expensive, this device (in the most simple terms) spins things. And spinning things like blood can separate out its components, allowing doctors to diagnose diseases like malaria. But the lack of electricity and resources in rural regions around the world means no centrifuge. Now, a simple new 20-cent gadget could change all that, and it's based on an unusual source of inspiration: the whirligig. %0D%0A%0D%0A"There are more than a billion people around the world who have no infrastructure, no roads, no electricity," says Manu Prakash, a physical biologist at Stanford and inventor of the new gadget. When he visited Uganda in 2013 he found that clinics either did not have centrifuges or didn't have the juice to power them. “One clinic used its broken centrifuge as a doorstop,” Prakash tells Devin Powell at Nature. %0D%0A%0D%0A%0D%0A"I realized that if we wanted to solve a critical problem like malaria diagnosis, we needed to design a human-powered centrifuge that costs less than a cup of coffee,” Prakash says in a press release. %0D%0A%0D%0AWhen he returned to Stanford, Parkash began brainstorming ideas with one of his post-docs, Saad Bhamla, examining at all sorts of spinning things, reports Madeline K. Sofia at NPR. They quickly began focusing on old-school, preindustrial toys like yo-yos and whirligigs. %0D%0A%0D%0A“One night I was playing with a button and string, and out of curiosity, I set up a high-speed camera to see how fast a button whirligig would spin. I couldn’t believe my eyes,” Bhamla says in the press release. The button was rotating at 10,000 to 15,000 rpms. %0D%0A%0D%0A%0D%0AThe pair began prototyping small hand-powered centrifuges based on the whirligig principle. Their final model, the Paperfuge, spins at 125,000 rpm, the equivalent of a centrifuge costing $1,000 to $5,000, according to the press release. %0D%0A%0D%0AThe Paperfuge is made of a disk of paper coated in a polymer, reports Sofia. The disk is attached to two pieces of wood or PVC pipe via string. When the strings are pulled, the disk in the middle spins, acting as a centrifuge for a blood sample attached to the center of the disk. The team describes their work in the journal Nature Biomedical Engineering. %0D%0A%0D%0APrakash and Bhamla recently returned from successful field trials of the Paperfuge in Madagascar where they used it to test for malaria. While the gadget only takes two minutes to separate blood, reports The Economist, it takes 15 minutes of whirligigging for malaria-diagnosing separations. %0D%0A%0D%0A%0D%0AOnce the blood is separated, however, it needs to be examined by a microscope. Luckily, several years ago Prakash also created the Foldscope, a $1 paper microscope with optical quality similar to conventional microscopes that will begin distribution in 2018.

The innovative approach taken by Manu Prakash and Saad Bhamla to tackle malaria diagnosis in resource-limited settings highlights the intersection of basic science and practical application. The Paperfuge, their human-powered centrifuge, serves as a game-changing tool designed specifically for areas lacking access to traditional, electricity-dependent medical equipment.

By utilizing the principles observed in simple toys like whirligigs, Prakash and Bhamla engineered an affordable and efficient solution that can spin at astonishing speeds, vastly outperforming standard laboratory centrifuges within a portable and economical package. This development reduces the cost barrier for necessary medical technologies, enabling significant progress in diagnosing and treating malaria, especially in rural hospitals that previously relied on inadequate or non-existent laboratory equipment.

The successful field trials in Madagascar underscore the practical effectiveness of the Paperfuge, which, despite requiring a longer whirling time compared to standard centrifuges, provides prompt and crucial separation of blood samples for further examination. With the additional implementation of the Foldscope, also designed by Prakash for affordable microscopy, the duo not only addresses the need for sample separation but also equips medical personnel with an affordable method to analyze samples directly.

Overall, this inventive method presents a beacon of hope in the global fight against malaria, demonstrating how creativity and inspiration drawn from everyday objects can lead to solutions that enhance healthcare accessibility in underserved regions. By leveraging the basic mechanics of playthings, Prakash and Bhamla open doors to crucial diagnostics that could save countless lives.
