Nanoparticles with synthetic DNA can control release of active agents — ScienceDaily

Medications often have unwanted side-effects. One reason is that they reach not only the unhealthy cells for which they are intended, but also reach and have an impact on healthy cells. Researchers at the Technical University of Munich (TUM), working together with the KTH Royal Institute of Technology in Stockholm, have developed a stable nano-carrier for medications. A special mechanism makes sure the drugs are only released in diseased cells.

The human body is made up of billions of cells. In the case of cancer, the genome of several of these cells is changed pathologically so that the cells divide in an uncontrolled manner. The cause of virus infections is also found within the affected cells. During chemotherapy for example, drugs are used to try to destroy these cells. However, the therapy impacts the entire body, damaging healthy cells as well and resulting in side effects which are sometimes quite
