US scientists have developed a new polymer that has a unique capacity to remove pollutant substances from water “in seconds.” The discovery could revolutionize the water-purification industry, make the process cheaper, and involve minimum energy.

A team of researchers from Cornell University made the breakthrough. The full research has been published in Journal Nature this week.

“What we did is make the first high-surface-area material made of cyclodextrin [sugar molecules bound together in a ring],” said Will Dichtel, associate professor of chemistry, who led the research, “combining some of the advantages of the activated carbon with the inherent advantages of the cyclodextrin.”
