Even if you don't know what 3D microfluidic networks are, that doesn't change the fact that they have some very valuable possible uses. Scientists have now devised a much easier method of making the things, by taking casts of plant roots.

Even if you don’t know what 3D microfluidic networks are, that doesn’t change the fact that they have some very valuable possible uses. Scientists have now devised a much easier method of making the things, by taking casts of plant roots.

Taking the concept a step further, the scientists experimented with growing fungi in the media instead of plants. It was found that the organisms’ extremely fine root structure, known as hyphae, formed channels in the glass as narrow as 1 micrometer.
