to remove from painted surfaces and may leave behind undesirable residues.

The new nanomagnetic sponges made from nanoparticles so small that about 10,000 would fit across the diameter of a human hair overcome that problem, the report states. The sponges can be loaded with solvents and other cleaning agents, and cut with a knife or scissors into desired shapes for application to specific, soiled areas of a painting. When the cleaning is done, conservators can remove the gel with a magnet. The nanomagnetic gel represents the most advanced and versatile system for cleaning and will have a dramatic impact on the conventional methods used in the conservation field and in several other fields where fine tuning of the release or uptake of confined material is required, the report states.

ARTICLE #3 FOR IMMEDIATE RELEASE

Tiny carbon nanotubes show big germ-fighting potential
Langmuir

In nanosciences version of a David-and-Goliath story, scientists in Connecticut are reporting the first direct evidence that carbon nanotubes have powerful antimicrobial activity, a discovery that could help fight the growing problem of antibiotic resistant infections. Their research on so-called single-walled carbon nanotubes (SWNTs) i
