A DNA–gold nanoparticle hybrid hydrogel network prepared by enzymatic reaction†
Abstract
We report a DNA–gold nanoparticle (AuNP) hybrid hydrogel in which the AuNPs crosslink enzymatically synthesized DNA to form a gel network. PCR-elongated DNA and AuNPs act as a one-dimensional polymer and cross-linkers, respectively. The DNA–AuNP hydrogel has the functional properties of both long DNA and the AuNPs.
