Planting the seed for DNA nanoconstructs that grow to the micron scale

by Harvard University

Strictly seed (green)-dependent crisscross polymerization enables the formation of diversely shaped tubes and coiled ribbons (grey), whereby elongating ribbons with different diameters are closed in different patterns by short complimentary single-stranded DNA overhangs (yellow and blue). This series of TEM images shows a variety of elongated nanoconstructs with the scale bar measuring 100 nanometers. Credit: Wyss Institute at Harvard University
