Ferromagnetic Resonance Biosensor for Homogeneous and Volumetric Detection of DNA.

ACS Sens; 2018 Jun 11.
Artículo en Inglés | MEDLINE | ID: mdl-29847920
The ability to detect and analyze the state of magnetic labels with high sensitivity is of crucial importance for developing magnetic biosensors. In this work, we demonstrate, for the first time, a ferromagnetic resonance (FMR) based homogeneous and volumetric biosensor for magnetic label detection. Two different isothermal amplification methods, i.e., rolling circle amplification (RCA) and loop-mediated isothermal amplification (LAMP), are adopted and combined with a standard electron paramagne
