Trackable drug-filled nanoparticles -- a potential weapon against cancer
Date:2/28/2013

ast. They showed through experiments on cultivated cells that the particles, while harmless in themselves, are effective at killing cancer cells when loaded with the drug.

The next step is to develop the system to target brain tumours, pancreatic cancer and drug-resistant breast cancer tumours, which are currently difficult to treat effectively with chemotherapy.

"Adding targeting groups to the surface or by changing the size of or adding ionic groups to our nanoparticles will make it possible to increase the selective uptake of these particles in tumours," says Dr Andreas Nystrm, Associate Professor in nanomedicine at the Swedish Medical Nanoscience Center, part of Karolinska Institutet's Department of Neuroscience.

It is hoped that one day this research will lead to tailored chemotherapy treatments that specifically seek out tumour cells. In that the drug, which is toxic to the body, can be delivered more precisely to the tumour, the treatment can be made much more effective with greatly reduced side-effects.
