According to New Scientist, researchers from the University of Twente in the Netherlands made the Pyramid shaped cage by depositing nitrides over silicon pits, a technique called corner lithography.
Because the pyramids are close together and have holes in the side, the cells can interact as they naturally do and can be easily observed.
Aart van Apeldoorn, one of the researchers, said:
“The thing is because they’re so open, [cells] can easily make connections to the outside. The 3D surface is more or less mimicking how cells act in actual tissues. Everything in our body is three-dimensional.”
