Siva Vanapalli and colleagues at Texas Tech University have developed a one-step passive strategy to create concentration gradients in static droplet arrays. Their recent Lab on a Chip article has been reported in PhysOrg.com, which discusses the implications of the technology for the future of drug testing.

Samuel Stavis and colleagues at the National Institute of Standards and Technology (NIST) have developed a nanoscale fluidic channel shaped like a staircase, which can be used to control the direction of drift of a DNA molecule through a fluid. An article in Nanotechnology Now discusses how this ‘nanoslinky’ presents new possibilities for manipulating and measuring DNA.
