DURHAM, N.C. -- A magnetic separation technique developed by researchers at Duke University's Pratt School of Engineering and Purdue University makes it relatively simple to sort through beads ...

Magnetic separation has become increasingly popular in biomedical science and industry. This technology uses magnetic properties of micro/nano-sized particles to separate macromolecules of interest, ...

Traditional magnetic separators, however, present a challenge: they generate a magnetic force that is very high near the side of the vessel closest to the magnet and decreases rapidly with distance.

MIT engineers have come up with a method of extracting clean water and reusable oil from oil spills using nanoparticles that turn the oil into magnetic ferrofluids. When oil spills occur, the polluted ...
