Introduction of gold

The application of gold in biomedicine can be dated back to ancient civilization of thousands of years ago. For example, India, Egypt and China had already use medicines containing gold. In China, the earliest application of gold was in treatment of smallpox, skin ulcer and rash. According to the Chinese traditional medical concept of "the channel circulation theory that gold is able to penetrate into hand" and both Dao and foot are channels. In Japan, people put gold slice into tea, sake and food, which is beneficial for health. Since gold has excellent biocompatibility, it can be directly applied in medical apparatus, such as gold alloy in artificial teeth and cardiovascular stent (wires for pacemakers and gold plated stents) in treatment of heart disease. Many surgeons like to use gold stent, because it has superior visibility in X-ray and this technology can also be applied in developing agent during medical examination. Another application of gold in medicine is the "medicine transmission microchip". Containers with medicine or other chemicals are covered by gold film and then sealed, followed by implant, swallow or intravenous inject the medicine and integrate microchips in the body system. The medicine dose is controlled by a small voltage, which releases the medicine from the gold container with the releasing time controlled by a doctor or patient through a microprocessor or a remote control device or biosensors.
