Recently, paper-based substrates have been proposed as an alternative to commonly used activated glass slides for microarray patterning, used in conjunction with capillary driven lateral flow of sample and detection reagents through the membrane. While fluorescent detection reagents may be employed to achieve high sensitivity, gold nanoparticles can also be used to allow readout by means of common table top scanners or digital cameras. Here, we demonstrate first results from employing a dendritic, or layer-by-layer, amplification approach for a high-density lateral flow allergen protein microarray, indicating that substantially increased sensitivity can be achieved with very modest increase of assay handling and time requirements.
