Abstract: Provided are methods of labeling and analyzing features along at least one macromolecule such as a linear biopolymer, including methods of mapping the distribution and frequency of specific sequence motifs or the chemical or proteomic modification state of such sequence motifs along individual unfolded nucleic acid molecules. The present invention also provides methods of identifying signature patterns of sequence or epigenetic variations along such labeled macromolecules for direct massive parallel single molecule level analysis. The present invention also provides systems suitable for high throughput analysis of such labeled macromolecules.

Abstract: Methods of analyzing features such as the physical size of macromolecules or biomarkers along large genomic DNA molecules were disclosed as wen as the devices for carrying out such high throughput analysis in a massively parallel fashion.

Abstract: The present invention provides methods of obtaining structural information about a biopolymer sample. The methods include labeling portions of a biopolymer, such as DNA or RNA, linearizing the biopolymer in some cases, and determining the distance between the labels. The user can then compare different samples' between-label distances to qualitatively compare different samples and to assay a given sample for additions or deletions of nucleotides in the regions flanked by the labels. The methods also permit sequencing of biopolymers.

Abstract: The present invention relates to a device for interfacing nanofluidic and microfluidic components suitable for use in performing high throughput macromolecular analysis. Diffraction gradient lithography (DGL) is used to form a gradient interface between a microfluidic area and a nanofluidic area. The gradient interface area reduces the local entropic barrier to nanochannels formed in the nanofluidic area. In one embodiment, the gradient interface area is formed of lateral spatial gradient structures for narrowing the cross section of a value from the micron to the nanometer length scale. In another embodiment, the gradient interface area is formed of a vertical sloped gradient structure. Additionally, the gradient structure can provide both a lateral and vertical gradient.
