Single particle ICP-MS-based absolute and relative quantification of<i>E. coli</i>O157 16S rRNA using sandwich hybridization capture

Abstract

Herein, a novel 16S rRNA detection platform was achieved by combining a sandwich hybridization reaction, a single-molecule magnetic capture, and single particle-inductively coupled plasma mass spectrometry amplification. The assay was developed for the direct detection of RNA from dangerous human pathogens and enabled absolute and high-precision quantification of a target with a detection limit of 10 fM.
