This device has several advantages over existing tests which currently only measure survival rates in bacteria. Yeast is ideal in detecting cancerous chemicals because its DNA-damage response system is remarkably similar to human cells. It can also be used to detect other types of damage such as oxidative stress with a high degree of accuracy. The device can be effectively used in continuous, high intensity screening programmes. DNA damage to yeast cells is detected by using a green fluorescent protein reporter that is abundant in living cells and reagent free. The device is highly efficient where DNA-damaging agents can be detected within one hour and simultaneous measurements can be recorded. With further research into the causes of cancer, the search for a cure becomes more refined. This device, which detects cancerous chemicals can also be used to detect dangerous components in water supplies and for compound screening.
