Micro rheometer is latest Lab On a Chip device

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a microminiaturised device that can make complex viscosity measurements - critical data for a wide variety of fields dealing with things that have to flow - on sample sizes as small as a few nanolitres. Currently a table-top prototype, the NIST rheometer could be a particularly valuable tool for biotechnologists studying minute quantities of complex materials that must function in confined spaces...
