METHOD FOR PREPARING MICRO-CHANNEL ARRAY PLATE, DEVICE FOR OBTAINING LIQUID DROPS USING THE MICRO-CHANNEL ARRAY PLATE, AND METHOD FOR GENERATING LIQUID DROPS

摘要

A method for preparing a micro-channel array plate, comprising: (1) arranging a first optical fiber glass rod and a second optical fiber glass rod closely, and melting the two glass rods at high temperature into a whole to obtain a melted glass rod, drawing the melted glass rod at least one time into a longer and finer glass rod than the melted glass rod, and cutting the fine-drawn glass rod into small pieces to obtain a micro-channel array plate blank, wherein the corrosion resistance of the first optical fiber glass rod and the second optical fiber glass rod to the same corrosive liquid is different; (2) corroding the micro-channel array plate blank by using corrosive liquid to obtain a micro-channel array plate crude product with through holes; and (3) conducting hydrophobic treatment on the micro-channel array plate crude product to obtain the micro-channel array plate.
