Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

ates" not only prevented chemical leakage, but also added weight to the nanoparticles, enabling their delivery into the plant cell with the standard gene gun.

The biologists successfully used the technology to introduce DNA and chemicals to Arabidopsis, tobacco and corn plants.

"The most tremendous advantage is that you can deliver several things into a plant cell at the same time and release them whenever you want," Torney said.

"Until now, you were at nature’s mercy when you delivered a gene into a cell," Lin said. "There’s been no precise control as to whether the cells will actually incorporate the gene and express the consequent protein. With this technology, we may be able to control the whole sequence in the future."

And once you get inside the plant cell wall, it opens up "whole new possibilities," Wang said.

"We really don’t know what’s going on inside the cell. We’re on the outside looking in. This gets us inside where we can study the biology per se," Wang said.
