Magnetic particle-based ultrasensitive biosensors for diagnostics

Expert Review of Molecular Diagnostics, 2012
The process of sensitive and accurate detection of small quantities of disease biomarkers is critical for the clinical diagnosis of disease. In this regard, magnetic particles (MPs) have been widely used because of their unique magnetic properties allowing for efficient target capture, enrichment and convenient separation.

Magnetic Permeability Measurements in Bioanalysis and Biosensors

Analytical Chemistry, 1996
A new transducer concept in bioanalysis and biosensors, utilizing measurements of magnetic permeability, is reported. A model system based on dextran ferrofluid, concanavalin A immobilized to a carrier (Sepharose), and glucose was used to demonstrate the feasibility of this approach. Direct ferromagnetic detection of the dextran ferrofluid was achieved

Magnetic biosensor technologies for medical applications: a review

Medical & Biological Engineering & Computing, 2010
In this review we discuss conventional methods of performing biological assays and molecular identification and highlight their advantages and limitations. An alternative approach based on magnetic nanotechnology is then presented. Firstly, magnetic carriers are introduced and their biocompatibility and functionalisation discussed, with spotlights on ...

CRP determination based on a novel magnetic biosensor

Biosensors and Bioelectronics, 2007
The c-reactive protein (CRP) is a very significant human blood marker for inflammatory processes and is routinely determined for many clinical purposes. The widespread and well established detection method for this approximately 115 kDa hepatic protein is the high-sensitivity ELISA assay (hsCRP-ELISA) in blood serum.
