MU researcher developing nano-scale molecules to image, treat different diseases

Nanomedicine is the medical application of nanotechnology, or the use of microscopic structures to diagnose, image, treat and prevent disease. Current problems in nanomedicine include understanding and anticipating the potentially toxic impact these nanostructures have on the body and the environment once they're released.

Chinese and American researchers introduce new approach to gene therapy

Resistance of tumor cells toward multiple cytostatic drugs is a serious problem in cancer treatment. In the journal Angewandte Chemie, a team of Chinese and American researchers has now introduced a new approach to gene therapy that could counter this problem: The gene that codes for resistance is “silenced” through the use of an ingenious nanocomplex.

New technique could help researchers unlock the secrets of respiratory syncytial virus

By the time they're two, most children have had respiratory syncytial virus and suffered symptoms no worse than a bad cold. But for some children, especially premature babies and those with underlying health conditions, RSV can lead to pneumonia and bronchitis - which can require hospitalization and have long-term consequences.
