3D bio-engineering with magnetic fields.

Problem: growing 3D biological tissues on 2D surfaces flattens the tissues and harms their natural properties.
Solution: float the growing tissues in a magnetic field.

Dec 14, 2011. MTR - Now a new technology, pioneered by Houston-based n3D Biosciences, promises to float cells in a 3-D matrix made of nothing but magnetism.

The secret ingredient is a proprietary mix of nanoparticles the company calls Nanoshuttle. The addition of these particles to a dish of living cells allows them to move in response to magnetic fields that can be varied in three dimensions and across time.

Injection of magnetic particles to improve control over a clump of matter was one of G.Altshuller's favorite problem-solving techniques. There's a whole set of recommended solutions based on this principle in Substance-Field "standards." (in Russian)
