Wireless microgrippers grab living cells in 'biopsy' tests
Researchers at Johns Hopkins University have invented wireless microgrippers that can be used to grab and remove living cells from hard-to-reach places. The devices are actuated by thermal or biochemical signals, eliminating the need for electrical wires, tubes, or batteries.
