Researchers at the Vienna University of Technology (TU Wien) in Austria have developed a high-resolution bioprinting process with completely new materials, involving the use of a special "bio ink" for three-dimensional (3D) printing.

The technique allows cells to be embedded in a 3D matrix printed with micrometer precision, at a speed of one meter per second.

Depending on how the structure is built, it can be made stiffer or softer; even fine continuous gradients are possible.

As a result, it is possible to define the structure to allow the desired kind of cell growth and cell migration.

Said TU Wien's Aleksandr Ovsianikov, "Using these 3D scaffolds, it is possible to investigate the behavior of cells with previously unattainable accuracy."
