Specifically, the inner wall of the specimen chamber 111 is coated with an antistatic sterilization layer, and the antistatic sterilization layer can enable the inner wall of the specimen chamber 111 to have an antistatic effect and a sterilization effect.
In specific implementation, when the sample 3 does not enter the sample chamber 111 through the sample inlet 121, the interior of the sample chamber 111 is communicated with the outside, and the inner wall of the sample chamber 111 has an antistatic effect, that is, the inner wall of the sample chamber 111 does not form an electrostatic magnetic force effect, and does not actively adsorb external dust and bacteria, and the inner wall of the sample chamber 111 has a sterilization effect, and can kill the bacteria adsorbed on the inner wall of the sample chamber 111, thereby ensuring the sanitation of the sample chamber 111 and avoiding pollution to the sample 3.
In the embodiment of the invention, the antistatic sterilization layer is composed of a plurality of nano metal mineral crystals, and the nano metal mineral crystals are tetrapod-like zinc oxide whiskers.
The tetrapod-like zinc oxide whisker is an antistatic high polymer material, and experiments prove that under the action of an electric field, the tip of the tetrapod-like zinc oxide whisker can generate an electric core concentration effect and a tunnel effect, so that the tetrapod-like zinc oxide whisker has a conductive characteristic and achieves an antistatic effect; in addition, under the condition of the same amount of the tetrapod-like zinc oxide whiskers, the resistance in the coating is lower than that in the plastic or rubber, so that the coating has better conductivity and achieves better antistatic effect, because: the tetrapod-like zinc oxide whiskers in the coating are hardly damaged and are completely and uniformly dispersed in the coating, and in the latter two cases, especially in rubber processing, because the material flowability is poor and the shearing force in the mixing process is also large, the tetrapod-like zinc oxide whiskers are partially damaged into single needles, even needle-like bodies are broken, and the formation of a conductive channel is influenced.
The outermost layer of the bacteria is synthesized with a layer of cell walls, and the cell walls of the bacteria are colorless, transparent, tough and elastic membrane walls and account for 10-40% of the total dry weight of the bacteria; due to refractivity and difficult dyeing; so that it is difficult to see under an optical microscope, and its main function is to maintain the appearance of bacteria and protect bacteria; most antibiotics, such as penicillin, inhibit peptidoglycan in bacterial cell walls, blocking the ability of microorganisms to build cell walls, thereby rendering the bacteria non-viable by losing their protective barrier. It is known that the purpose of sterilization can be achieved by inhibiting the synthesis of cell walls by bacteria or destroying the synthesized cell walls. The tetrapod-like zinc oxide whiskers in the crystals have four radial needle bodies, and the needle points have the capability of piercing the cell walls of bacteria through a nanocrystallization process, so that when the bacteria are adsorbed on the inner wall of the sample chamber 111, the needle points of the tetrapod-like zinc oxide whiskers can smoothly pierce the cell walls of the bacteria, the bacteria can die naturally due to the loss of a protective barrier, and the aim of sterilization is fulfilled.
