  • Patent number: 9308529
    Abstract: The present invention relates to method of using a microfluidic chip for rapid nucleic acid hybridization, comprising: activating a porous substrate with positive charges; injecting a mixed solution of a test nucleic acid and a nucleic acid probe into the microfluidic chip for maintaining the test nucleic acid hybridized to the nucleic acid probe being absorbed to the periphery of the substrate; continuously washing the microfluidic chip with an anionic surfactant; and detecting the hybridization signals on the substrate after washing for a predetermined time; wherein the activation of the substrate with positive charges allows the test nucleic acid hybridized to the nucleic acid probe to form a micelle during washing and the diffusion of such from the periphery toward the center of the substrate to accelerate. Thus, it is possible to accomplish detection in a very short time for application of specific DNA complementary hybridization.

  • Patent number: 8148066
    Abstract: The present invention relates to a nucleic acid hybridization method and in particular to a method using a microfluidic chip-based hybridization device with modified procedures which shows the advantages of simplicity and efficiency. The method of the present invention is to mix the test nucleic acid and the probe nucleic acid in advance, feed the solution into a hybridization device with a porous substrate, let the nucleic acid to be analyzed absorb into the substrate. The washing solution is then injected into the same device to wash out the unhybridized probes and the signals of hybridization absorbed on the substrate are detected for analysis. The conventional 2-step approach for the hybridization of the nucleic acid to be analyzed and the probe is combined into one step by the method of the invention provided here, which simplifies the necessary steps and shorten the time needed for hybridization reaction and detection.

  • Publication number: 20100112714
    Abstract: The present invention relates to a biochip for nucleic acid hybridization. The biochip of the present invention comprises a hybridization chamber which is in the form of a cavity, a porous membrane pressed in the hybridization chamber; and at least one first circulation hole and at least one second circulation hole which are communicated with the hybridization chamber so that the reaction solution flows in the at least one first circulation hole and flows out the at least one second circulation hole through the pores of the porous membrane. The hybridization reaction area is increased by flowing the reaction solution through the pores of the membrane, which enable the reaction sensitivity to be increased. The diffusion distance for the reaction molecules is decreased due to the limited inside space of the membrane, and thereby the hybridization time is shortened.

  • Patent number: 7501250
    Abstract: The present invention relates to a blotting method for rapidly analyzing nucleic acid comprising the steps of transferring a nucleic acid to be analyzed to the substrate and fixing the nucleic acid to be analyzed absorbed on the substrate; directing adding a nucleic acid probe to hybridize in a short time, without blocking the areas where the nucleic acid to be analyzed has not been fixed; removing the nucleic acid probe which has not been annealed to the nucleic acid to be analyzed by washing; and finally detecting the hybridization signal. According to the present invention, since the prehybridization is not needed and the hybridization and washing time is shortened, the time for the nucleic acid hybridization is dramatically shortened. Therefore, the whole blotting procedures for rapidly analyzing nucleic acid may be finished quickly.
