[TD]The body's immune system exists to identify and destroy foreign objects, whether they are bacteria, viruses, flecks of dirt or splinters. Unfortunately, nanoparticles designed to deliver drugs, and implanted devices like pacemakers or artificial joints, are just as foreign and subject to the same response.
Now, researchers at the University of Pennsylvania School of Engineering and Applied Science and Penn's Institute for Translational Medicine and Therapeutics have figured out a way to provide a "passport" for such therapeutic devices, enabling them to get past the body's security system.
The research was conducted by professor Dennis Discher, graduate students Pia Rodriguez, Takamasa Harada, David Christian and Richard K. Tsai and postdoctoral fellow Diego Pantano of the Molecular and Cell Biophysics Lab in Chemical and Biomolecular Engineering at Penn.[/TD]

This could have huge implications for delivery system that would otherwise be destroyed by the bodies defences.

Nano machines.
This may be completely retarded, But what if by some chance, a virus gains access to this "Passport"?

there are viruses that hide behind your bodies defences by appearing to be the body or part of it rather, i'm going to have to google it but i'm sure of this

somewhat similar concept but there's more than this to that concept for viruses, it's just like a trojan horse, not a foreign concept to viruses

I wouldn't doubt it, viruses are constantly mutating.

Maybe the nanoparticles are too small to contain a virus?

They're just peptides.. :v:
