Researchers Find Way To Align Gold Nanorods On A Large Scale, North Carolina State University Study


8/19/2011 8:30:38 AM

Researchers from North Carolina State University have developed a simple, scalable way to align gold nanorods, particles with optical properties that could be used for emerging biomedical imaging technologies.Aligning gold nanorods is important because they respond to light differently, depending on the direction in which the nanorods are pointed. To control the optical response of the nanorods, researchers want to ensure that all of the nanorods are aligned. The NC State researchers developed a way to align the gold nanorods using electrospun polymer “nano/microfibers.” Electrospinning is a way of producing fibers, with a liquid polymer being discharged from a needle and then solidifying. The researchers produced fibers as thin as 40 nanometers (nm) in diameter and as thick as three microns in diameter – thus, nano/microfibers.
