AI Technical Summary

Technical Problem

Existing sample holders are difficult to quickly and efficiently detect and count small objects, such as biological particles, molecules, cells, etc. in sample analysis.

Method used

A sample holder is designed, which includes an upper layer, a lower layer and an intermediate layer, through holes in the intermediate layer forming a sample chamber and covering a hydrophobic surface on partial edges of the upper layer and the lower layer to prevent liquid leakage.

Benefits of technology

Through the design of the hydrophobic surface, the sample chamber can effectively seal the sample liquid, prevent liquid from flowing out, and allow gas exchange, improving the accuracy and efficiency of sample analysis.

Abstract

The sample holder (10) comprises a sample chamber (33), a gas storage tank (32), and an upper layer (20) covering the sample chamber (33) and the gas storage tank (32), wherein the bottom surface of the upper layer (20) comprises a microstructure array (23) covering at least a portion of the top periphery of the sample chamber (33), and wherein the microstructure array (23) is connected to a gas passage extending to the gas storage tank (32) to allow gas exchange between the sample chamber (33) and the gas storage tank (32).
