a Descriptions of different liquid states under the micropore membrane in five regions (R1–R5). b–d Observed different red ink droplet movements in the three regions: b R2, droplets were drawn into the membrane, c R3, droplets were held still, and d R4, more liquid was drawn by droplet out to flow along the membrane
