CRISPR/Cas13a Powered Portable Electrochemiluminescence Chip for Ultrasensitive and Specific MiRNA Detection.

ABSTRACT: MicroRNAs (miRNAs) have been widely investigated as potential biomarkers for early clinical diagnosis of cancer. Developing an miRNA detection platform with high specificity, sensitivity, and exploitability is always necessary. Electrochemiluminescence (ECL) is an electrogenerated chemiluminescence technology that greatly decreases background noise and improves detection sensitivity. The development of a paper-based ECL biosensor further makes ECL suitable for point-of-care detection. Recently, clustered regularly interspaced short palindromic repeats (CRISPR)/Cas13a as high-fidelity, efficient, and programmable CRISPR RNA (crRNA) guided RNase has brought a next-generation biosensing technology. However, existing CRISPR/Cas13a based detection often faces a trade-off between sensitivity and
