Sensitive and specific detection of nucleic acids can be achieved using a chemical ligation-based template assisted rapid assay (TARA-L) with simple chemical reactions between probes and without the need for enzymes. Probes are designed to form a ligation product when they anneal to adjacent portions of a target nucleic acid. The ligation products can be detected, such as in immunochromatographic assays. The methods allow for the fast, efficient analysis of biological samples for the presence of nucleic acids and can be used, for example, in point of care settings.
