| Keywords: Nanofluidics; 3-D (5887831448).jpg A Schematic of the NIST-Cornell nanofluidic device with complex 3-D surfaces Each step of the staircase seen on the side marks a different depth within the chamber The letter E shows the direction of the electric field used to move the nanoparticles through the device The green balls are spheres with diameters of 100 nanometers whose size restricts them from moving into the shallower regions of the chamber The coil in the deep end of the chamber upper right corner is a single DNA strand that elongates upper left corner in the shallow end B Photomicrograph showing fluorescently tagged spherical nanoparticles stopped at the 100-nanometer level of the chamber the depth that corresponds to their diameter C Photomicrograph of a single DNA strand that is coiled in the deep end of chamber box at far right and elongated in the shallow end box at far left Larger boxes are closeups showing the fluorescently tagged strands Credit NIST Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/5887831448/ Nanofluidics; 3-D 2009-04-03 12 17 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/5887831448 2016-09-07 02 32 48 United States Government Work Uncategorized 2016 November 30 | ||||
