Stretching DNA and molecules in a systematic manner

Unique patterns generate when two immiscible fluids flow together and this has been a factor for scientists to develop a new tool for studying tiny biomolecules.Researchers at the National Taiwan University and the National Central University in Taiwan used a technique called two-phase microfluidics to stretch organic molecules in a systematic manner. The researchers produced various types of flow patterns by controlling the flow rate ratio of two fluids, and the Reynolds number, which is a ratio between the inertial and viscous forces in a fluid. Stretching polymers, proteins, DNA, and other organic macromolecules can reveal important details about molecule makeup and molecule interaction with other substances.
