Level 1 - Absolute Beginner
Engineers made a new material. It is made from tiny drops of water.
The material works like human body tissue. It can sort and filter tiny particles.
You can print this material with a 3D printer. It only takes a few minutes to make.
This new material could help doctors heal people. It could also help build robots and clean dirty water.

Level 2 - Elementary
Engineers at the University of Texas at Austin have developed a new 3D-printable material that mimics the way human tissue sorts and filters molecules.
The material is formed by tightly packing billions of tiny water droplets, each separated by a thin membrane. Using simple mixing and spinning techniques, researchers can create large, tissue-like structures in just a few minutes.
Because the material can be tuned with different proteins, it can be designed to selectively let certain ions or molecules pass through while blocking others, much like a real biological membrane.
The research team says the material is biocompatible, meaning it is safe to use inside the body, and could be applied in tissue repair, soft robotics, and even pulling valuable minerals out of wastewater.

Level 3 - Intermediate
Engineers at the University of Texas at Austin have developed a new 3D-printable material that replicates the ability of human tissue to selectively sort and filter molecules, a capability with potential applications across medicine, robotics, and environmental engineering.
The material is constructed from billions of tightly packed water droplets, each separated by a thin membrane, using straightforward mixing and centrifuge techniques that allow researchers to form large, tissue-like structures within minutes rather than through slow, complex fabrication processes.
Because the droplet network can be tuned with specific proteins, the material can be engineered for targeted ion conduction or to recognize particular molecules, closely paralleling the selective transport mechanisms found in biological membranes.
The research team, whose work was published in the journal Nature Materials, demonstrated that adding a particular protein allowed the material to distinguish ammonium from other ions in wastewater, pointing toward a practical approach for recovering critical minerals and nutrients from water that would otherwise be discarded.

Level 4 - Advanced
Engineers at the University of Texas at Austin have developed a novel 3D-printable material that replicates the capacity of human tissue to selectively sort and filter molecules, a capability with prospective applications spanning medicine, soft robotics, and environmental engineering.
The material is constructed from billions of tightly packed water droplets, each partitioned by a thin membrane, fabricated through comparatively straightforward mixing and centrifugation techniques that allow researchers to assemble large, tissue-like structures within minutes rather than through the protracted, labor-intensive processes typical of biomimetic material fabrication.
Because the droplet network can be functionalized with specific proteins, the material can be engineered for targeted ion conduction or molecular recognition, closely paralleling the selective transport mechanisms intrinsic to biological membranes.
The research team, whose findings appear in the journal Nature Materials, demonstrated that incorporating a particular protein enabled the material to discriminate ammonium from other ions present in wastewater, pointing toward a viable pathway for recovering critical minerals and nutrients from water streams that would otherwise be discarded as waste.
