New studies show how scientists have honed a technique for handling tiny, soft particles using precisely controlled fluid flows that act as gentle microscopic hands
This finding could lead to soft robotics, liquid circuitry, shape-shifting fluids, and a host of new materials that use soft, rather than solid, substances
A technique called acoustic force spectroscopy uses standing sound waves in a fluid channel to tug on DNA and other biomolecules in a precise and easily controllable way, revealing information about the molecules' structure and mechanical properties
