Scientists use 3D printing to make artificial blood vessels

The tangled highway of blood vessels that twists and turns inside our bodies, delivering essential nutrients and disposing of hazardous waste to keep our organs working properly has been a conundrum for scientists trying ...

Graphene-coated heart valves could sidestep harmful drugs

Every year thousands of people are fitted with artificial heart valves to replace their own malfunctioning valve. Many of these patients, however, have to remain on drugs that stop blood clotting on these artificial valves. ...

Cellulose with Braille for cells

Artificial implants such as pacemakers often cause complications because the body identifies them as foreign objects. Researchers at ETH Zurich have now demonstrated a simple method to fabricate cellulose-sheaths for implants, ...

Rapidly building arteries that produce biochemical signals

Duke engineers have developed a technique to make artificial arteries that naturally produce biochemical signals vital to their functions. The technique is also ten times faster than current methods for tissue engineering ...
