Scientists develop gentle, microscopic hands to study tiny, soft materials

Handling very soft, delicate items without damaging them is hard enough with human hands, let alone doing it at the microscopic scale with laboratory instruments. Three 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. The technique allows researchers to test the physical limits of these soft particles and the things made from them -- ranging from biological tissues to fabric softeners.
