Graphene oxide nanoscrolls to benefit water treatment techniques

Researchers at MIT and Harvard University fabricated nanoscrolls made from graphene oxide flakes for water purification applications, at a much lower cost than that of graphene membranes. The team was able to control the dimensions of each nanoscroll, using both low- and high-frequency ultrasonic techniques.

The researchers say that these nanoscrolls could also be used as ultralight chemical sensors, drug delivery vehicles, and hydrogen storage platforms, in addition to water filters. Also, the ability to tune the dimensions of these architectures may open a window to industry, in combination with the more affordable production costs.
