Libraries are not exempt from the nanotechnology invasion. Research on coating paper with zinc oxide (ZnO) nanoparticles for their antibacterial effects is now underway. It is expected that this technology will be applied in the papermaking industry in the next decade, therefore affecting all new print materials in libraries. In addition, nanoparticles are now being used in electronic inks and in the manufacturing of electronic papers, the main components of e-book readers. Nanochips are also being used in our desktop computers, and will soon be extensively used in almost all electronic and wireless equipment. Questions about nanotechnology safety are everywhere.
