Nanoparticle structures could help agriculture

Researchers are working to develop the “next generation” of insecticides that delivers active ingredients directly to pests

In Hollywood, a movie about nanotechnology would probably feature an army of tiny robots threatening to destroy the world.

Then Ryan Reynolds and Sandra Bullock would show up to defeat the evil scientist who invented the robots.

In the real world, nanotechnology is much different.

It’s founded on chemistry. And the scientists aren’t evil.

“When people hear nanotechnology, they often think of these little robots,” said Justin Pahara, an Agriculture Canada researcher in Lethbridge.

“We’re able to build very small structures. By no means are we creating these little, intelligent robots.”
