Silicon can be developed into a biocompatible and biodegradable material that could lead to smaller, smarter and more-interactive implants in the human body. The secret: “porous” silicon – bulk silicon that has been deliberately riddled with nanometer-sized holes.
Rather than having to shield a silicon-based device from body tissues and the bloodstream, it is now theoretically possible to construct silicon-based devices that are genuinely “bioactive.”
The surface of a… read more
