The interaction between silver nanoparticles and viruses is attracting great interest due to the potential antiviral activity of these particles, and is the subject of much research effort in the treatment of infectious diseases. In this work, we demonstrate that silver nanoparticles undergo a size-dependent interaction with herpes simplex virus types 1 and 2 and with human parainfluenza virus ...

The artificial fusion of cells of different type and species, for the formation of heterokaryons and hybrid cells, is now widely used, since Harris and Watkins (1965) demonstrated the practicality of this technique, with Sendai virus as a fusing agent. A variety of viruses show fusing properties (Poste, 1972)) but in most artificial systems Sendai virus (parainfluenza virus type 1) has been use...
