US researchers say tiny carbon particles, or 'nanodiamonds', can help treat late-stage breast and liver cancer tumours

WASHINGTON - US RESEARCHERS said on Wednesday they have found a way to attack late-stage breast and liver cancer tumours by attaching a potent chemotherapy drug to tiny carbon particles known as nanodiamonds. The technique was tested in mice and showed that nanodiamonds helped the drug, doxorubicin, get inside the normally chemo-resistant tumour and shrink it, said the study published in the journal Science Translational Medicine. Without the nanodiamonds, the drug was either rejected by the body and failed to work on the tumour, or in higher doses it was too powerful for the patient to survive. 'This is the first work to demonstrate the significance and translational potential of nanodiamonds in the treatment of chemotherapy-resistant cancers,' said the study. The research shows promise for possible use in humans because chemotherapy drug resistance causes treatment to fa...
