Scientists have created the tiniest "tweezers" known to date, which
can move around objects the size of single molecules with a "bow tie" of
light.
"To my knowledge these are the smallest tweezers ever built," physicist Mathieu Juan, from Sydney's Macquarie University, told the Australian Broadcasting Corp. "They will allow people to manipulate, scan and move around very small objects such as viruses."
