Fairly straightforward question: Why are nanoparticles generally made using metal, that too generally using gold, silver etc?

I think it's because it's relatively easy. Any physics department can quite readily set up a lab to produce and measure metal nanoparticles. But I suppose the technical reason is that metals can melt and form droplets, which then solidify as nanoparticles. Ceramics and organic materials don't necessarily melt and evaporate as well.

Yeah, I'm no nanoperson, but I'd go with 'ease'. Faraday famously figured out how to make gold and silver nanoparticles 150 years ago.

Ease of formation is not the only reason. These nanoparticles have use as biosensors and other lab-on-chip sensors due to the phenomenon of surface plasmon resonance.
