Abstract: The present invention provides methods to barcode nucleic acid for detection and sequencing. It applies a barcode template in a compartment with various targets, including nucleic acid fragments, nuclei and/or cells. After clonal amplification within the compartment, barcode sequence will integrate into its targets before the compartment is broken so that it will effectively barcode nucleic acid fragments originated from a nucleic acid fragment, a nucleus or a cell clonally. The barcode information can be used for tracking the origin of the fragment, nucleus or cell and be used for haplotype phasing and a variety of single cell-based applications including whole genome sequencing, targeted sequencing, RNA sequencing and immune repertoire sequencing.

Abstract: The present disclosure relates generally to methods of controlling the movement of molecules, such as DNA (Deoxyribonucleic Acid), RNA (Ribonucleic Acid) and proteins as well as other biological molecules passing through nanopores. In particular, the disclosure describes how structures made of soft magnetic material can be used to selectively hold, pull and release DNA tagged with magnetic beads.

Abstract: The present disclosure provides methods and compositions for tracking nucleic acid fragment origin by target-specific barcode tagging when original nucleic acid targets break into small fragments. Nucleic acid targets are captured in vitro on a solid support with clonally localized nucleic acid barcode templates. Many nucleic acid targets can be processed simultaneously in a massively parallel fashion without partition. These nucleic acid target tracking methods can be used for a variety of applications in both whole genome sequencing and targeted sequencing in order to accurately identify genomic variants, haplotype phasing and assembly, for example.

Abstract: The present disclosure provides methods and kits for tracking nucleic acid target origin by barcode tagging of the targets when they break into smaller fragments. Nucleic acid targets are captured in vitro by clonally localized nucleic acid barcode templates on a solid support. Millions of nucleic acid targets can be processed simultaneously in a massively parallel fashion without additional partition. These captured targets are broken into small fragments, and a target specific barcode sequence is tagged on each fragment as an identification of their original target. These nucleic acid target tracking methods can be used for a variety of applications in both whole genome sequencing and targeted sequencing.

Abstract: The present invention is related to engineered nucleic acid bases for use in molecular electronics, such as nanosensors, molecular-scale transistors, FET devices, molecular motors, logic and memory devices, and nanogap electronic measuring devices for the identification and/or sequencing of biopolymers.

Abstract: The present disclosure provides methods for high throughput barcoding nucleic acids and/or protein inside the cells. The in-cell single cell capture method uses an individual cell itself as a compartment and delivers a plurality of unique identifiers, e.g., barcodes into the cell and captures the nucleic acid and/or protein targets within the cell directly. It significantly simplifies single cell analysis experimental setup and eliminates the need of external compartment generation. It provides a high throughput single cell expression profiling and cellular protein quantitation method, and targeted sequencing with in-cell capture will be able to significantly increase sensitivity and specificity for low frequent mutation detection, such as, somatic mutation in very early stage of cancer and truly enables early cancer detection. A spatial expression and/or variation detection method for a tissue sample is developed with the combination of the in-cell barcoding method and positional barcode on a planar array.
