Label-Free Biosensors for the Detection and Quantification of Cardiovascular Risk Markers
This paper presents a biosensor implementation for the detection of protein molecules using specific antibodies. Affinity sensors allow the detection and quantification of target molecules in complex mixtures by affinity-based interactions. Immobilized antibody molecules are the probes that bind to specific protein molecules (targets) in biological fluids. In this study, inter-digitated electrodes in the form of capacitance on glass slide were designed, fabricated and used to measure the changes in the dielectric properties of the inter-digitated capacitances. Our results in this study present that with a careful design of micro-interdigitated capacitors, a wider dynamic range and higher sensitivity can be achieved for the detection and quantification of C-Reactive Protein.
