DNA-Mediated rolling circle amplification for ultrasensitive detection of thrombin using MALDI-TOF mass spectrometry†
Abstract
A DNA-mediated rolling circle amplification (RCA) strategy was established for ultrasensitive and specific detection of thrombin via matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). This platform provides a versatile assay for the detection of various biomolecules of low abundance.
