A method of sterilizing objects as well as the sterilized objects obtained from the method are disclosed. The method involves contacting an object such as a medical device to be reused with polycationic dendrimer under conditions which result in rendering a conformationally altered protein (e.g. a prion) non-infectious. A disinfecting agent or surgical scrub composition which comprises the dendrimers is also disclosed as are gelatin capsules treated with polycationic dendrimers.

L'invention concerne également un agent désinfectant ou une composition pour brossage chirurgical renfermant ces dendrimères, sous forme de capsules de gélatine traitées à l'aide desdits dendrimères.
