Utilising antibodies labelled with paramagnetic nanoparticles (Magnetic ImmunoAssay, MIA) is a novel means of increasing the sensitivity and precision of lateral flow immunoassays while enabling the development of an inexpensive robust reader. The magnetic particles can be detected and quantified with great accuracy while the direct interaction between the magnetically labelled antibodies and the reader’s electronics creates a system unique in its sensitivity and robustness. Furthermore, magnetometers have a wider dynamic ranges then optical systems, reducing the need for sample dilution while retaining sensitivity. This presentation will describe the application of this technology to a clinically important analyte; C-reactive protein.
