Nano Sunscreen Guide [28]
Here's a great resource to find nano sunscreens (well, it seems like a good resource for anyone interested in protecting their skin). They list the active component in the sunscreen and if it uses Zinc Oxide or TiO2, it'll say if it's less than 100 nm. If you notice, all the highly rated sunscreens use nanoparticles.
