title: Aptamer based reversible DNA induced hydrogel system for molecular recognition and separation.
abstract: An aptamer-based DNA strand, captured with a specific molecule from a multi-species system, was used to initiate crosslinking of the hydrogel. The hydrogel can then be dissolved with a displacement of the DNA strand and the captured molecule can be released. Recognition and separation at the molecular level is thus achieved.
