Congratulations to Meg Catterton for putting out a great paper. You can read about her cool SlipChip for movable stimulation of lymph nodes and other tissue slices online today in Lab on a Chip. This technology enables the user to move a microfluidic port to a desired location under a slice of tissue or 3D culture of cells, and deliver solution just to that spot. We hope it will be useful for many other researchers who are interested in local events in live tissue. Contact us if you are interested in testing it out!
