An electromagnetic device can gently sort cells by levitating them to different heights. It looks like a magic trick: cells at the bottom of a liquid medium begin levitating, then hovering at a ...

Poly(N-isopropylacrylamide) (PNIPAM) hydrogel undergoes significant but precise changes in size between 20°C and 40°C, making it an excellent candidate for use in variable-size deterministic lateral ...

Stanford Medicine researchers invent an electromagnetic device that can gently sort different types of cells by levitating them to different heights. It looks like a magic trick: Cells at the bottom ...

It looks like a magic trick: Cells at the bottom of a liquid medium begin levitating, then hovering at a particular height. With no physical contact, an invisible force directs certain cells to float ...

Using an array of poly(N-isopropylacrylamide) (PNIPAM) micropillars whose size varies precisely with temperature, this device can be precisely tuned to sort cells across a range of sizes.
