A Cross-Linking Approach to Stabilizing Stimuli-Responsive Colloidal Crystals Engineered with DNA
Abstract
Two DNA-cross-linking reagents, bis-chloroethylnitrosourea and 8-methoxypsoralen, are used to covalently cross-link interstrand base pairs in DNA bonds that, in part, define colloidal crystals engineered with DNA. The irreversible linkages formed increase the chemical and thermal stability of the crystals and do not significantly affect their long-range order, as evidenced by small-angle X-ray scattering data. The post-modified crystals are …
