Objective To construct SDA piezoelectric DNA sensor array and solve the problem of insufficient detection flux of SDA piezoelectric DNA sensor. Method 1 Using sensor integration technology, 10 SDA piezoelectric DNA sensors were fabricated into 2×5 sensor array chips.2 The detection of S.tuberculosis isolate IS61 10 was used to study the characteristics of SDA piezoelectric DNA sensor array. Results The sensor microcells of the sensor array chip can work independently from each other and do not interfere with each other. Conclusion The array of SDA piezoelectric DNA sensors does not affect the performance of the sensor. At the same time, the detection throughput of the SDA piezoelectric DNA sensor is improved to a certain extent, making the SDA piezoelectric DNA sensing technology more clinically practical.
