Building superlattices from individual nanoparticles via template-confined DNA-mediated assembly
Abstract
A polymer pore template can control the order of assembly of nanoparticles into well-defined stacks and create superlattices. Lin et al. used DNA strands on gold nanoparticles to control interparticle distance. The DNA strands contained modified adenines with more rigid ribose groups that formed stronger base pairs. The height of the stacks of three different types of gold nanoparticle could be changed with different solvents, which in turn changed their optical response.
