Abstract: A method and apparatus designed for nucleic acid hybridization employs a hydrogen bond denaturation area with a higher temperature and a lower temperature nucleic acid hybridization area that is immobilized with nucleic acid probes. Nucleic acid-containing samples are introduced into the hydrogen bond denaturation area for heating curled nucleic acids in samples so that they become linear and are guided into the nucleic acid hybridization area. In this area, the nucleic acid hybridization rate can be multiplied by increasing the kinetic energy by the repeated flow of driven fluid. The nucleic acid hybridization apparatus provided by the invention contains a hydrogen bond denaturation area, a nucleic acid hybridization area, a two-way driving apparatus, and a temperature control element.

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.
