Researchers at Purdue University have created a magnetic "ferropaper"
that might be used to make low-cost "micromotors" for surgical
instruments, tiny tweezers to study cells and miniature speakers.
The material is made by impregnating ordinary paper -- even newsprint
-- with a mixture of mineral oil and "magnetic nanoparticles" of iron
oxide. The nanoparticle-laden paper can then be moved using a magnetic field.
"Paper is a porous matrix, so you can load a lot of this material
into it," said Babak Ziaie, a professor of electrical and computer
engineering and biomedical engineering.
