A microchip for bio sensor use in the field of Point of Care Testing has been produced. The chip will be used in a biosensor system with an integrated bilayer lipid membrane being attached to an electrode on the chip. Ligand gated ion channels incorporated into the membrane provide the biological recognition.
Silver-enhanced labeling method that is employed in immunochromatographic assay provides an effective way of improving the sensitivity of detecting pathogens. In this paper, we apply the silver enhancement approach for providing signal amplification in conductimetric biochips which employ gold nanoparticles to bridge on a high-density microelectrode array for detecting gold nanoparticles. One of the...
A label-free biosensor based on localized surface plasmon resonance (LSPR) was developed. A multi-channel microfluidic chip was integrated with the sensor, providing referencing channel to minimize noise level and improving the throughput. With a CCD as a detector, a sensitivity of 10-4 RIU was demonstrated. The adsorption of S-layer protein was detected successfully by the sensor system.
