Fabrication of 3D microvascular networks by plant cultivation method. (a) Process flow of the proposed technique. A plant seed is cultivated on a culture medium containing silica nanoparticles. After cultivation, the sample is heat-sintered to remove the plant while transcribing its root structure into hollow microchannels within a transparent glass chip. (b) Sample view during plant cultivation stage. (c) Sintered glass chip containing replicated root channels after heat treatment. (d) Optical micrograph of the transparent glass chip, showing the root-shaped microchannels resembling a live plant.
