High sensitivity detection of Hepatitis B virus RNA based on 3D-DNA nanomachine and protein nanopore sensing.

ABSTRACT: Serum Hepatitis B virus (HBV) RNA serves as a non-invasive biomarker for monitoring chronic hepatitis B and guiding treatment decisions. However, current diagnostic tests relying on Reverse Transcription Quantitative Polymerase Chain Reaction (RT-qPCR) require centralized facilities and tedious operational steps, and there is currently no standardized HBV RNA detection method. Herein, we describe the rapid amplification-free detection of HBV RNA in clinical serum samples via a nanopore sensing method. Our method involves the design of a DNA nanomachine capable of translation of each target HBV RNA into a large amount of 7-nt single-strand DNA (ssDNA) as signal reporters that produce blockage features when passing through an alpha-hemolysin (α-HL) nanopore, the target can be quantified by i
