[0031] figure 1 It is a top view of the structure for constructing the test microenvironment shown according to the first embodiment. Such as figure 1 As shown, the structure for constructing a test microenvironment in this embodiment includes a microporous matrix 1 and a first channel 11 and a second channel 12 formed inside the microporous matrix 1 .
[0032] The microporous matrix 1 is one of hydrogel, microporous molecular sieve, microporous foam, and microporous ceramics. Preferably, the microporous matrix 1 is a hydrogel, which is hydrophilic and provides suitable micropore size. Also flexible, hydrogel materials include, but are not limited to, hyaluronic acid, chitosan, polyacrylic acid, polymethacrylic acid, polyacrylamide, poly-N-polyacrylamide, and the like. Optionally, the micropore diameter of the microporous matrix 1 is 0.1 nm-1 μm, the inner diameters of the first channel 11 and the second channel 12 are 0.1 mm-5 mm, and the thickness of the microporous matrix...

[0043] Figure 5 It is a top view of a structure for constructing a test microenvironment shown according to the second embodiment. Such as Figure 5 As shown, the structure for constructing a test microenvironment in this embodiment includes a microporous matrix 3 and a first channel 31 and a second channel 32 formed inside the microporous matrix 3 .
[0044] The main difference from the first embodiment is that the first channel 31 and the second channel 32 of this embodiment each include an annular portion, and the annular portion of the first channel 31 and the annular portion of the second channel 32 are arranged concentrically. The annular portions of a channel 31 and the second channel 32 are arranged alternately, that is, there is a annular portion of the second channel 32 between two adjacent annular portions of the first channel 31 .
[0045] The range of heating and humidification can be effectively limited by the annular parts of the first passage 31 and the seco...

[0048] Image 6 It is a cross-sectional view of the structure for constructing the test microenvironment according to the third embodiment when it is in use. Such as Image 6 As shown, the structure for constructing the test microenvironment in this embodiment includes a shell. The difference from the first embodiment is that the microporous matrix 4 is accommodated in the shell 42, and the side of the shell 42 facing the area to be tested is open.
[0049] The side of the microporous substrate 4 facing the area to be tested is provided with a micro-protrusion structure 43, and the microporous substrate 4 contacts the surface of the chip 2 or the chip wiring pin through the micro-protrusion structure 43, while ensuring that the microporous substrate 4 and the chip 2 Or the surface of the chip wiring pin has a certain microspace, which improves the uniformity of the microenvironment.
[0050] The shell 42 can be prepared by chitosan material or organic material such as polydi...
