Protein Microarray-Guided Development of a Highly Sensitive and Specific Dipstick Assay for Glanders Serodiagnostics.

Burkholderia mallei, the causative agent of glanders, is a clonal descendant of Burkholderia pseudomallei, the causative agent of melioidosis, which has lost its environmental reservoir and has a restricted host range. Despite limitations in terms of sensitivity and specificity, complement fixation is still the official diagnostic test for glanders. Therefore, new tools are needed for diagnostics and to study the B.

Melioidosis DS rapid test: A standardized serological dipstick assay with increased sensitivity and reliability due to multiplex detection.

Background: Melioidosis, caused by Burkholderia pseudomallei, is a severe infectious disease with high mortality rates, but is under-recognized worldwide. In endemic areas, there is a great need for simple, low-cost and rapid diagnostic tools. In a previous study we showed, that a protein multiplex array with 20 B.

Carboxyl functionalized gold nanorods for sensitive visual detection of biomolecules.

Antibody-modified gold nanomaterials are central to many novel biosensing technologies for example the lateral flow assays technology. The combination of the specificity, provided by antibody-antigen interactions, and the unique optical properties of nanomaterials provide excellent properties for biosensors. Here, we present the use of gold nanorods (GNR) with the localized Surface Plasmon Resonance (LSPR) peak in the visible range for biomarker detection.
