Researchers at Commerce’s National Institute of Standards and Technology (NIST) have created an innovative device called the “microfluidic palette” to produce multiple, steady-state chemical gradients—gradual changes in concentration across an area—in a miniature chamber about the diameter of a pinhead. The tool can be used to study the complex biological mechanisms in cells responsible for cancer metastasis, wound healing, biofilm formation and other fluid-related processes. (More)
