IBM Researchers Demonstrate New Method for Rapid Molecule Sorting and Delivery

To demonstrate the positioning precision of IBM's new atomic force microscope (AFM) molecule sorting and delivery technique, the IBM researchers transferred 5-base-long DNA segments onto a chemically modified silicon surface to form the IBM corporate logo. The narrow line width ranged from 59-79 nanometers. The image is also created by the same AFM, which detected the average 2.4-namoeter height of the deposited DNA segments. The logo measured 3.3 by 8.8 microns. More than 300 of these logos would fit onto the cross section of a human hair. Credit: IBM
