Abstract:
... Anti-idiotypic nanobodies (AId-Nbs) are novel antigens that can replace the conventional hapten–protein conjugates of small molecule toxins, serving the same function in the competitive immunoassay. Furthermore, nanobodies show increased sensitivity from naïve (non immunized) phage display libraries because those obtained have a lower affinity than the binding affinity of the target analytes. Here ...

Abstract:
... To fabricate the conductive composites with the low resistivity required for conductive films, a multi-layer network of AgNWs must be produced which may not be cost effective. Recently, we have counteracted the problem by using AgNWs and Ag-microsheets to form novel overlapping-junctions-nanostructures, which can significantly improve the electrical properties of conductive films. Subsequently, lo ...
