A packing device used to pack a sample inlet formed in an upper cover of a chamber is provided. The packing device has an air vent formed in the surface of an upper portion of the sample inlet contacting a cap or in the surface of a lower portion of the cap contacting the sample inlet. The movement of the sample solution in the chamber can be prevented by using a structural design in which air pressure generated due to the volume of a packing cap inserted into the sample inlet after the sample is injected into the chamber through the sample inlet to react with reaction materials, such as biomolecules, is not generated inside of the chamber. In addition, in a hybridization chamber in which a biochip is placed, the spot area on the biochip can be effectively agitated with the sample solution, thus increasing hybridization efficiency.

Provided is a lysis method for cells or viruses, including: immobilizing a metal-ligand complex on a solid support; and mixing the complex immobilized on the support with a cell or virus solution. According to the lysis method, by immobilizing a chemical on a solid support to perform cell lysis, the dilution problem according to the addition of a cell lysis solution can be resolved and a separate process of removing the chemical is not required so as to reduce the steps upon LOC implementation. In addition, since a variety of solid supports, such as chips, beads, nanoparticles etc. can be used, cell lysis apparatuses of various forms can be fabricated.
