What if you could shrink your technology down to a size that’s 100,000 times smaller than the width of a human hair? It sounds like sci-fi, but it’s not. Romain Quidant shows us how he helped shrink an entire medical laboratory down to the size of a computer chip. The “lab on a chip” uses molecular mini-detectives to track down diseases hiding within a tiny drop of blood. We’ll find out how it works, and why a tiny particle could make a big difference for human health. To see a photo of Romain holding the lab on the chip, check out our blog at sciencepodcastforkids.com/blog. Tumble is brought to you with support from KiwiCo.
