Atomic force microscopy image of as-deposited (left) and laser-annealed (right) rGO (bottom) thin films. The entire "pulsed laser annealing" process is done at room temperature and atmospheric pressure using high-power nanosecond laser pulses to "melt" the rGO material; it is completed in about 200 nanoseconds.

Graphene sheets allow for very-low-cost diagnostic devices

March 20, 2017

Mild heating of graphene oxide sheets makes it possible to bond particular compounds to the sheets’ surface, a new study shows. These compounds in turn select and bond with specific molecules of interest, including DNA and proteins, or even whole cells. In this image the treated graphene oxide on the right is nearly twice as efficient at capturing cells as the untreated material on the left. (credit: Courtesy of the researchers)
