摘要：

Next generation sequencing (NGS) is revolutionizing all fields of biological research but it fails to extract the full range of information associated with genetic material. Optical mapping of DNA grants access to genetic and epigenetic information on individual DNA molecules up to similar to 1 Mbp in length. Fluorescent labeling of specific sequence motifs, epigenetic marks and other genomic information on individual DNA molecules generates a high content optical barcode along the DNA. By stretching the DNA to a linear configuration this barcode may be directly visualized by fluorescence microscopy. We discuss the advances of these methods in light of recent developments in nano-fabrication and super-resolution optical imaging (nanoscopy) and review the latest achievements of optical mapping in the context of genomic analysis.
