Piero Baglioni, a chemist at the University of Florence, Italy, and colleagues have described a new technology - "nanomagnetc sponges" - to clean works of art. Their works is described in a recently published article in ACS' Langmuir journal. This new technology is using a gel, which is a polymer (polyethylene glycol and acrylamide), impregnated with iron nanoparticles. The product can be cut into "sponges" with any shape the conservator may need. After cleaning, the remains of the gel are simply removed by a magnet.
