About this work

Description

Rod-shaped, gold nanoparticles, when coated with a cancer antibody, are effective at binding to tumour cells and can be used in the diagnosis and treatment of cancer. When bound to the gold, the cancer cells scatter light, making it very easy to identify the noncancerous cells from the malignant ones. The particles are 30-90nanometres in length.
