Mimicking the structure of the kidney, scientists from Lawrence Livermore National Laboratory and the University of Illinois at Chicago have created a three-dimensional nanometer-thin membrane composed of two 3D interconnected channels, which are separated by a nanometer-thin porous titanium oxide layer. This unique biomimetic 3D architecture dramatically increases the surface area, and thus the filtration area, by 6,000 times, coupled with an ultra-short diffusion distance through the 2–4 nanometer-thin selective layer.
