When Mark A. Skylar-Scott says he and his Harvard University colleagues can make metal filaments in midair, he stresses that they aren’t defying gravity. The team’s silver strands start attached to a substrate, but the researchers can draw them out through three-dimensional space to create intricate patterns. Led by Skylar-Scott and Jennifer A. Lewis, the researchers are forging the 3-D silver wires on demand using a nanoparticle ink and laser light . . .
