Performance Optimization of Microvalves Based on a Microhole Array for Microfluidic Chips
Effects of microstructural parameters on the contact angle and the residual rate of the absorbent in microfluidic chips. (a) Effect of the diameter of the microhole on the results and h = 95 μm and a = 250 μm. (b) Effect of the depth of the microhole on the results and d = 230 μm and a = 250 μm. (c) Effect of the center distance of the microholes on the results and d = 230 μm and h = 95 μm. (d) Relationship between the residual rate and the contact angle results.
