Modern medicine strikes gold

MUMBAI, MAY 3:

Beyond the popular association with jewellery and investment, gold is finding a critical use in healthcare, from diagnosing illnesses such as malaria to newer uses such as targeting and treating tumours.

Nano-particles or miniscule particles of gold are increasingly used in rapid tests to diagnose malaria, for example — a development that is interesting for India, says Trevor Keel, World Gold Council's technology head.

These are simple rapid generic kits containing very small gold quantities to test urine or blood and, because they are easy to handle, they can be used at remote locations that are not close to a healthcare facility, he explains.
