An Indian-origin scientist and colleagues have developed a new technology to measure single biological molecules with unprecedented accuracy and precision which can provide high-resolution data from microscopes.

Researchers from Iowa State University and Ames Laboratory in the US have blended optical and atomic force microscope technologies to develop complete 3-Dimensional measurements of single biological molecules.
The new microscope technology is called standing wave axial nanometry (SWAN).

An Iowa State assistant professor of physics and astronomy and an associate of the US Department of Energy's Ames Laboratory Sanjeevi Sivasankar told reporters that this is a completely new type of measurement which enable scientists to detect the height of the molecule with nanometer accuracy and precision.
