Lucknow, May 6 -- Scientists at the Council of Scientific and Industrial Research - Central Drug Research Institute (CSIR-CDRI) have come up with a new mechanism that on one hand enhances the efficacy of an anti-cancer drug, while also stopping the drug from attacking normal cells, in the treatment of breast cancer.

Manish Chourasia, a scientist who was involved in the research said, "We have prepared a double-shell magnetic nanoparticle system which can attack cancer-causing cells without affecting normal cells. These nanoparticles attach to the drug - for eg, Doxorubicin - a common drug used during chemotherapy. On one hand, it can increase efficacy and also reduce the toxicity of the drugs," said Chourasia.

He underscored that iron-d...
