Researchers at Singapore’s Institute of Bioengineering and Nanotechnology (IBN) have developed a simple method of organizing cells and their microenvironments in hydrogel fibers. Their unique technology provides a feasible template for assembling complex structures, such as liver and fat tissues.
Researchers from NIST (the National Institute of Standards and Technology) and the University of North Carolina have designed a new "instrumented nanoscale indenter" to improve the accuracy of sensitive measurements of thin film surface properties.
A novel chip-scale instrument made from carbon nanotubes may simplify absolute measurements of laser power. Developers of the unit at the National Institute of Standards and Technology (NIST) say it may prove especially useful for measuring light signals transmitted by optical fibers in telecom networks.
