Abstract
The invention provides miniaturized lateral flow chromatographic and lateral flow chromatographic microarray devices (LFM). The miniaturization of lateral flow nucleic acid detection achieved by the present invention offers reduced reagent use, femtomole sensitivity, excellent linear dynamic range, and rapid detection. Moreover, the small feature sizes of capture oligonucleotides renders the potential information capacity of the platform comparable to more traditional spotted fluorescence microarrays as well as improving sensitivity. The LFM devices exemplified herein enable analytes to be detected within 10 seconds from the time of sample introduction to the LFM device. Sample volumes may be as low as about 10 microliters, significantly reducing assay costs and ameliorating reagent storage logistics. Additionally, the miniaturization of lateral flow opens the door to highly multiplexed assays, allowing many proteins or nucleic acids to be detected in a single assay.
