Methods and arrays for identifying the cell or tissue origin of DNA are provided. Accordingly there is provided a method of identifying DNA having a methylation pattern distinctive of a cell or tissue type or state comprising: labeling an epigenetic modification of interest in a DNA sample with a label; contacting said sample on an array comprising a plurality of probes for said DNA under conditions which allow specific hybridization between said plurality of probes and said DNA; and detecting said hybridization, wherein an amount of said label is indicative of the cell or tissue type or state, wherein the method is effected in the absence of amplification of said DNA.

The present disclosure relates to a structure capable of simultaneously purifying and detecting a nucleic acid by directly applying a sample, and more particularly, to a structure capable of performing sample preparation, loop-mediated isothermal amplification, detection and analysis steps on a single chip by applying lab-on-paper technology, and capable of finally determining whether the disease or bacterial is infected by moving the sample in a lateral flow method and immediately being connected to genetic big data related to disease and bacterial infection.

A method of forming a polymer matrix array includes treating a surface within a well of a well array with a surface compound including a surface reactive functional group and a radical-forming distal group; applying an aqueous solution including polymer precursors to the well of the well array; and activating the radical-forming distal group of the surface coupling compound with an initiator and atom transfer radical polymerization (ATRP) catalyst to initiate radical polymerization of the polymer precursors within the well of the well array to form the polymer matrix array.
