Cover Feature: An Origami Paper-Based Analytical Device Coupled with Fast-Responding Functional RNA Superstructures for Tetracycline Detection (Anal. Sens. 3/2023)

Abstract

The cover feature image shows a fast-responding gating system by using horseradish peroxidase (HRP)-loaded functional RNA superstructures (HRP@3D RNA). The specificity of RNA aptamer-ligand interaction serves as a triggered manner to release the loaded HRP from HRP@3D RNA. Based on this, a disposable origami paper-based analytical device (doPAD) was developed for tetracycline (TC) detection.
