Artificial, personalized tumors 3D bioprinted with magnets

A team of engineers from McMaster University (ON, Canada) has developed a novel method for the rapid 3D printing of cells, utilizing the magnetic properties of different materials, including cells. Engineers from McMaster University (ON, Canada), led by Ishwar Puri (McMaster University), have harnessed the magnetic properties of different materials - including cells - to develop a rapid 3D bioprinting technique. By suspending human breast cancer cells in a cell culture containing Gd-DTPA, a magnetic salt hydrate, the team was able to develop bioinks with magnetic properties. When a magnetic field was applied to the suspension, the magnetic salt moved...
