If you think the picture above looks like droplets of blood being snared in a sticky tentacle, then you have a scarily active -- but in this case accurate -- imagination. It's actually a microfluidic chip that's been coated with long strands of DNA, which dangle down into the bloodstream and bind to any cancerous proteins floating past -- directly imitating the way a jellyfish scoops up grub in the ocean. If required, the chip can release these cells unharmed for later inspection. According to the chip's designers at Boston's Brigham and Women's Hospital, the catch-and-release mechanism can be put to both diagnostic and therapeutic use in the fight against Big C, and can also be used to isolate good things, like fetal cells. The next step will be to test the device on humans -- at which point we may owe an even greater debt of gratitude to our gelatinous friends.
