Fig. 3: Characterization of the performance of BAS Mem when they were used to drive liquid and sample solution, including flow directionality of liquid, flow time of liquid, utilization rate of liquid, and residual sample solution on the membrane.
A Characterization of flow behavior of liquid on two types of membranes. A-i) Optical images show the flow behavior of liquid on two types of membranes. Scale bar = 5 mm.; A-ii) Comparison histogram shows the lengths of liquid flowing on two types of membranes; A-iii) Comparison histogram of the rectification coefficients between two types of membranes. B Optical images show the time-dependent flow of liquid on two types of membranes. Scale bar = 5 mm. C Comparison histogram shows the time of liquid flowing on two types of membranes. D Optical images show the flow of liquid in different volumes on two types of membranes. The black dashed lines marked in the image indicate the location of practical T and C lines. Scale bar = 5 mm. E Comparison histogram shows the lengths of 5 µL of liquid flowing on two types of membranes. F Optical images show the time-dependent flow of sample solution on two types of membranes, when the sample solution of Au-Ab was transported using mimic strips. Scale bar = 5 mm. G Curves show the time-dependent color intensity of Au-Ab on membranes. H Comparison histogram show the color intensity of Au-Ab that remained on BAS Mem and NC Mem (at 300 s). Data are presented as mean ± SD in A-ii (n = 3), A-iii (n = 3), C (n = 3), E (n = 3), H (n = 3, independent replicates).
