With magnetic immunodetection (MID), we can rapidly detect a wide range of substances directly at the point of sampling. Detection times from analyte addition to signal readout are typically under 30 minutes, making MID significantly faster than conventional ELISA, while also offering enhanced sensitivity compared to standard immunoassays.
For low-molecular-weight compounds such as mycotoxins or antibiotics, MID achieves detection limits in the nano- to picomolar range, while proteins like cholera toxin subunit B can be detected at 0.7 pg/mL. Beyond small molecules and proteins, a variety of pathogens—including viruses, fungi, and bacteria—can be reliably and quantitatively measured. By employing magnetic nanosensors, the method can also be combined with a pre-analytical magnetic purification and enrichment step for even greater precision.
