Abstract
Recent analytical innovations for nucleic acid detection have revolutionized the biological sciences. Single nucleic acid sequence detection methods have been expanded to incorporate multiplexed detection strategies. A variety of nucleic acid detection formats are now available that can address high throughput genomic interrogation. Many of these parallel detection platforms or arrays, employ fluorescence as the signaling method. Fluorescence-based assays offer many advantages, including increased sensitivity, safety and multiplexing capabilities, as well as the ability to measure multiple fluorescence properties. Multiplexed microarray platforms provide parallel detection capabilities capable of measuring thousands of simultaneous responses. This review will discuss both single target detection and microarray applications with a focus on gene expression and pathogenic microorganism (PM) detection.
