The paper aims to develop a rapid, simple and single copy gold immunochromatographic strip assay method for the quantitative determination of trace concentrations in serum or urine. The image of gold immunochromatographic strip is taken by CCD, and after a proper process, the reflective integral optical density is extracted as the feature based on Lambert-beer law. In order to improve the measure...
Silver-enhanced labeling is a technique used in immunochromatographic assays for improving the sensitivity of pathogen detection. In this paper, we employ the silver enhancement approach for constructing a biomolecular transistor that uses a high-density interdigitated electrode to detect rabbit IgG. We show that the response of the biomolecular transistor comprises of: (a) a sub-threshold region...
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...
