Lateral flow assays (LFA) are used for point-of-care qualitative diagnostics of an analyte of interest, often in non-laboratory environments. Traditionally, the format of a lateral flow assay utilizes immobilized antibodies on a membrane as the capture probe in conjunction with a reporting immunological recognition system for an analyte captured between them in a sandwich format. However, there are several shortcomings of antibodies which recommend their replacement with other recognition elements if possible. Among the reasons for seeking alternatives are the long time required to raise and identify a selective and strongly binding antibody, the cost of antibodies, their poor shelf …
