Why? Magnetite Nanocrystals are good for removing arsenic from water. Based on recent advances in nanotechnology, it’s now possible to make regular magnetite nanocrystals as small as 20-100nm, and to remove them from solution using a handheld magnet. Arsenic poisoning is a huge problem in Southeast Asia, especially in Bangladesh, and in various other parts of the world. Our project opens up the process for making magnetite and encourages you to experiment with it, contribute to it, and improve it.
