Fun GOLD facts (1 minute) No.21
Did you know that besides its use in treating arthritis, gold is also utilized in medical diagnostics and treatments? Radioactive gold isotopes, such as gold-198, are used in some forms of cancer treatment. These isotopes can be implanted directly into tumors to target cancer cells with minimal impact on surrounding healthy tissue, a technique known as brachytherapy. This precise targeting helps to reduce side effects and improve the effectiveness of cancer treatment.

Additionally, gold nanoparticles are being explored for their potential in detecting diseases at an early stage. These nanoparticles can be engineered to bind to specific biological markers, making them useful in imaging techniques like MRI and CT scans. This allows for the early detection of diseases such as cancer and Alzheimer's, potentially leading to earlier and more effective treatments. The versatility of gold in medicine highlights its importance beyond aesthetics, showcasing its critical role in advancing healthcare and saving lives.
