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.
