Liposome-encoded magnetic beads initiated by padlock exponential rolling circle amplification for portable and accurate quantification of microRNAs

Abstract

Development of reliable and affordable quantitative methods for miRNAs with high specificity and sensitivity is a central challenge to make miRNA testing a routine part of medical care with respect to cancer. Herein, we propose a strategy for glucoamylase-encapsulated liposome-encoded magnetic beads initiated by padlock exponential rolling circle amplification (P-ERCA) for portable and accurate quantification of miRNA by using a glucometer readout.
