All this happened, more or less.

By coating 30-nanometre-long chunks of tobacco mosaic virus with platinum nanoparticles, it’s possible to create a transistor with very fast switching speed. Millions of these transistors could eventually be used in a memory chip to replace flash memory in mp3 players and digital cameras, for example.

It could make an interesting sci-fi story to explore how viruses and computers co-evolve in the future.
Milieu: Virtual Underground Lab where game/world developers work on new battle characters;
Idea: An organism ( mutating virus) that can move freely between virtual and real world is used to physically affect players' environment/well-being;
Character: An "orphan" virtual character ( Wizard ) that keeps losing his/her owners due to real-life calamities.
Event: Members of the "real-life" technorati club assassinated without any trace.

How it works. Virtual characters trigger software behavior that mutates and then releases into the real world viruses/proteins, embedded into computer memory/processors, .
