Description

technical field [0001] The invention relates to the field of electronic device preparation, in particular to a low-cost and high-precision preparation method of carbon-based and metal-based electrode arrays. Background technique [0002] According to relevant statistics, the scale of my country's in vitro diagnostic market has reached tens of billions of RMB per year. At present, optical detection methods such as chemiluminescence are mostly used in in vitro diagnosis, and the detection cost is relatively high, and the core technology is monopolized by foreign multinational companies. Compared with optical methods, electrochemical sensing technology has the characteristics of portable equipment, convenient use, and low detection cost. The large-scale popularization of electrochemical blood glucose meters has proved its application advantages in low-cost, portable, and rapid biochemical analysis. However, the screen-printed carbon electrodes used in electrochemical blood glu...

Problems solved by technology

However, the above scheme also has deficiencies. Lee fixes the non-adhesive template to the surface of the filter membrane, and its filter device is complicated and difficult to apply to large-volume dilute solutions of conductive materials; Such schemes require the use of expensive wax-jet printers, the template membrane preparation process is relatively complicated, and the use of paraffin wax as the template material also has problems such as poor high-temperature stability.
