Abstract

DNA is in control: Different combinations of DNA nucleotides can control the shape and surface roughness of gold nanoparticles during their synthesis. These nanoparticles were synthesized in the presence of either homogenous oligonucleotides or mixed-base oligonucleotides using gold nanoprisms as seeds. The effect of the individual DNA bases and their combinations on shape control are shown in the figure.

摘要

DNA 掌控一切：在金纳米粒子的合成过程中，不同的 DNA 核苷酸组合可以控制其形状和表面粗糙度。这些纳米粒子是在均相寡核苷酸或混合碱基寡核苷酸的存在下，使用金纳米棱柱作为种子合成的。图中显示了单个 DNA 碱基及其组合对形状控制的影响。
