Australian scientists directly target cancer cells
An Australian biotechnology firm said on Thursday it had developed a means of delivering anti-cancer drugs directly to cancer cells, which aims to avoid the debilitating toxicity associated with chemotherapy.
The method uses nanotechnology, which involves micro-machines far smaller than a human cell.
Direct targeting of chemotherapy drugs would allow dosages thousands of times lower than that in conventional chemotherapy and be more easily tolerated by patients, said the firm.
Writing in the May issue of U.S.-based Cancer Cell magazine, the biotech firm EnGeneIC said it had developed nano-cells containing chemotherapy drugs.
