Microscopic pyramids can cage living cells

By

Researchers at the University of Twente have developed a way of trapping cells in microscopic pyramids.

According to the university, these pyramids allow the study of cells in a three dimensional environment. “Compounds and protein-like deposits were soon seen forming between cells in nearby pyramids. Changes in cell phenotype can therefore be studied better than in a flat plane, as this is the right way to grow cells. This yields a promising tool for research into such things as tissue regeneration.”

Building microscopic silicone pyramids was accidentally discovered. The technology can also be used to make microscopic writing utensils.
