DNAzyme crosslinked hydrogel: a new platform for visual detection of metal ions

Author affiliations

Abstract

We propose the use of DNAzyme as a crosslinker of hydrogel to develop a catalytic platform for the sensing of metal ions. The DNAzyme crosslinked hydrogel can undergo gel–sol transition in response to Cu2+ ions, which enables sensitive visual detection of Cu2+ by observing the release of pre-trapped AuNPs.
