Microfluidic droplet templates derived porous patch with anisotropic wettability

Biological patches with controllable surface wettability have received extensive attention in fundamental research and clinical practice. Herein, we present a novel Janus porous patch with anisotropic surface wettability derived from microfluidic droplet templates for wound healing. Such patch was fabricated by magnetic-induced assembly and replicating of hydrophilic and hydrophobic colloidosomes into a double-layered, close-packing film. The...
