Abstract

The invention relates to methods and devices for analyzing single molecules, i.e. nucleic acids. Such single molecules may be derived from natural samples, such as cells, tissues, soil, air and water without separating or enriching individual components. In certain aspects of the invention, the methods and devices are useful in performing nucleic acid sequence analysis by probe hybridization.
