Abstract:
A method of sequencing a plurality of template nucleotide sequences includes immobilizing the plurality of template nucleotide sequences on a substrate. A first subset of the plurality of template nucleotide sequences is immobilized in a first field of view and a second subset of the plurality of template nucleotide sequences is immobilized in a second field of view. The first and second subsets are hybridized to a caged primer. The caged primer includes a caging group. The method further includes lysing the caging group from the caged primer in the first field of view and observing the first field of view to detect sequencing of the first subset of the plurality of template nucleotide sequences.
Abstract:
In some embodiments, an analyte detection system is provided that includes a nanochannel, an electrode arrangement, and a plurality of nanoFET devices disposed in the nanochannel. A plurality of nucleic acid base detection components can be used that include a plurality of nanopores, a plurality of nanochannels, a plurality of hybridization probes, combinations thereof, and the like. According to other embodiments of the present teachings, different coded molecules are hybridized to a target DNA molecule and used to detect the presence of various sequences along the target molecule. A kit including mixtures of coded molecules is also provided. In some embodiments, devices including nanochannels, nanopores, and the like, are used for manipulating movement of DNA molecules, for example, in preparation for a DNA sequencing detection. Nanopore structures and methods of making the same are also provided as are methods of nucleic acid sequencing using the nanopore structures. Surface-modified nanopores are provided as are methods of making them. In some embodiments, surfaced-modified nanopores for slowing the translocation of single stranded DNA (ssDNA) through the nanopore are provided, as are nanopores configured to detect each of a plurality of different bases on an ssDNA strand.
Abstract:
Systems and methods for providing biomolecule interaction sites are disclosed. In certain embodiments, coupling of two or more different metal-nanoparticles can provide a significant increase in flexibility in controlling parameters associated with excitation of fluorophores attached to the biomolecules. Types and number of metal-nanoparticles and spatial arrangement of such nanoparticles are some of the parameters that can be adjusted to control fluorescence parameters such as excitation wavelengths and intensity of fluorescence. In certain embodiments, enhanced fluorescence effect can be confined to a sufficiently small region so as to allow sensing of one biomolecule at a time. Combined with enhanced fluorescence intensity, such small enhancement region can be used to perform processes such as real-time DNA sequencing.
