High-tech paint will block cell phone calls

Jon Van reports in Tribune:
A company called NaturalNano is developing a special high-tech paint that relies on the wizardry of nanotechnology to create a system that locks out unwanted cell phone signals on demand.

"You could use this in a concert hall, allowing cell phones to work before the concert and during breaks, but shutting them down during the performance," said Michael Riedlinger, president of NaturalNano of Rochester, N.Y.

His firm has found a way to use nanotechnology to blend particles of copper into paint that can be brushed onto walls and effectively deflect radio signals.
