A pure DNA hydrogel with stable catalytic ability produced by one-step rolling circle amplification

This is the authors' abstract. We don't add key points for this paper.

A rolling-circle-amplification method was developed to produce DNA hydrogels with horseradish-peroxidase-like catalytic capability. The catalytic hydrogel exhibits highly improved stability at elevated temperatures or during a long-term storage. Integrated with glucose oxidase, the complex hydrogel can be applied to the sensitive and reliable detection of glucose.
