Artificial pores has been invented by a group of scientists from the University of Buffalo. The professor Bing Gong who led the research tells that this is an extreme breakthrough that it might help us purifying the water, killing the tumor, regulating the substances in cells to cure a disease.

“The idea for this research originated from the biological world, from our hope to mimic biological structures, and we were thrilled by the results,” Gong says. “We have created the first quantitatively confirmed synthetic water channel. Few synthetic pores are so highly selective.”

It was created by a method to force doughnut-shaped molecules called rigid macrocycles to pile on top of one another, these stacks of molecules are then stitched with hydrogen bonding. The resulting structure was a nanotube with a pore less than a nanometer in diameter.

Atomic force microscopy images of artificial ion channels created by scientists. The images are of the same sample, with increasing magnification.

“This nanotube can be viewed as a stack of many, many rings,” says Xiao Cheng Zeng, professor of chemistry at the University of Nebraska-Lincoln and one of the study’s senior authors. “The rings come together through a process called self-assembly, and it’s very precise. It’s the first synthetic nanotube that has a very uniform diameter. It’s actually a sub-nanometer tube. It’s about 8.8 angstroms.”

(One angstrom is one-10th of a nanometer, which is one-billionth of a meter.)This wonder material could bring further breakthroughs in the field of medicine as a better and a simple way of treating diseases.
