Problems solved by technology

In addition, because the concentration of the captured target molecule is very low, the current signal that can be detected is also very weak, usually on the order of nanoampere or picoampere
However, in the existing detection equipment, generally only the detection of milliampere level can be achieved.

Embodiment Construction

[0050] Preferred embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Through the accompanying drawings and corresponding descriptions, those skilled in the art will further understand the features and advantages of the present invention.

[0051] figure 1 Shown is a holding structure 1 according to a first embodiment of the present invention, which is used to hold a sample detection orifice plate ( figure 1 not shown in ), the well plate carries the electrodes and holds the sample. The holding structure 1 may comprise a holder 10 . The holder 10 may include a holder body 100, which may have a receptacle 110 capable of receiving a well plate. The holder 10 may further include at least one probe module 200 disposed on the bottom 111 of the accommodating portion 110 . In this first embodiment, the holder 10 may include two probe modules 200 ( Figure 5 ).

[0052] The probe module 200 may include a pl...

Abstract

A holding structure used for holding a sample detection hole plate, the sample detection hole plate being used for accommodating a sample to be detected and being provided with an electrode, the holding structure comprising a holder and a pressure conversion plate, the holder comprising a holder main body provided with an accommodating portion for receiving the sample detection hole plate and a probe module arranged at the bottom of the accommodating portion, the sample detection hole plate being located between the pressure conversion plate and the probe module upon being received within the accommodating portion.

Description

technical field [0001] The invention relates to a holding structure for holding a sample detection hole plate, and to a detector comprising the holding structure. Background technique [0002] In the field of sample detection, especially in the field of liquid biopsy detection, an orifice plate with multiple holes is usually used to contain biological samples. The electrodes of the orifice plate are electrically connected to the bottom of the holes, so that the weak current signal of the biological sample It can be output to the signal detection processing unit outside the orifice plate through the electrodes. In addition, because the concentration of the captured target molecule is very low, the current signal that can be detected is also very weak, usually on the order of nanoampere or picoampere. However, in the currently existing detection equipment, it is generally only possible to detect the milliamp level. Therefore, a holding structure is needed, which can repeated...
