Abstract: Provided herein are synthetic nucleic acid molecules known as loop-mediated riboregulators that have single-nucleotide polymorphism (SNP) sensitivity and ultralow OFF state signal levels. Loop-mediated riboregulators can activate or repress gene expression in response to trigger RNAs bearing completely arbitrary sequences. Also provided herein are methods of using such synthetic nucleic acid molecules for detecting the presence or absence of a particular target RNA in, for example, a biological sample.

Abstract: Methods and compositions for detecting the presence of a pathogen are described. In particular, this document provides a method of detecting a pathogen-associated nucleic acid in a biological sample of a subject, where the method comprises using one or more unimolecular aptamer-based sensors comprising an aptamer-fluorophore complex and an amplification step to detect the pathogen-associated nucleic acid. Methods specific for detecting the presence of malaria and other mosquito-borne virus infections are also provided.

Abstract: Provided herein are methods and systems for low-cost, low-equipment detection of pathogens in biological sample. In particular, provided herein is a low-cost method for detecting norovirus that provides reliable, visible test with femtomolar, attomolar, and zeptomolar detection limits and that uses materials suitable for deployment of the methods in the field.
