Abstract: Disclosed are a chaotropic agent; a reagent including a chaotropic agent and a lithium salt; a reagent kit including a chaotropic agent; a chaotropic agent, a reagent, a reagent kit, and a method for isolating a nucleic acid by use of a magnetic cellulose material; a method for binding a nucleic acid to a magnetic cellulose material; a method for isolating a nucleic acid; and a method for purifying a chromosome DNA. It is required that each of the chaotropic agents, the reagents, and the reagent kits works with at least one solid-phase, magnetic cellulose-containing carrier to isolate a nucleic acid from non-nucleic acid substances. In addition, each chaotropic agent includes an alcohol substance and a substrate solution for adjusting the alcohol substance to an appropriate concentration and thereby promoting binding of the nucleic acid in a sample to the magnetic cellulose.

Abstract: The invention discloses an on-spot hydrophilic enhanced slide/microarray. The preparation method relates to a hydrophobic copolymer prepared by blending, grafting or co-polymerization of a hydrophobic material and a compound bearing functional groups such as anhydride, imide, cyclic amide, and cyclic ester, and application of the hydrophobic copolymer onto an organic or inorganic substrate. The resulting slide has the properties of on-spot hydrophilic/hydrophobic dynamic conversion, as well as on-spot hydrophilic enhancement for the preparation of high-density and high-efficiency bio-chip/microarray.

Abstract: The invention discloses a method for preparing an active slide, including introducing a monomer containing an aldehyde group, or a mixture of a monomer containing an aldehyde group and an acidic functional group provider into a plasma chamber; and depositing the aldehyde group and acidic functional group onto the surface of an organic or inorganic matrix using plasma deposition to form a slide comprising a layer of polymerized actively functional groups thereon. The aldehyde groups and negatively charged groups are deposited on the surface of the active slide, such that the bio-molecules bound thereto possess the properties of an inducible orientation and thus form a mono-layer.
