Researchers have developed a device that can limit the side effects of chemotherapy. The device uses tiny amounts of palladium to trigger reactions in cells, allowing the cancer drugs to be activated and delivered at the tumour site. The metal particles are able penetrate the cells without causing damage as they are coated. According to the researchers, the device can protect cancer patients from the hair loss, sickness and weakened immune systems associated with chemotherapy. Apart from delivering cancer drugs to the tumour site, the device can also be used to deliver dyes to organs for diagnostic tests, the researchers noted. The device has been developed by researchers at Edinburgh University, UK, in collaboration with Universiti Kebangsaan, Malaysia.
