10nm gives the best results I've been able to get. Silica particles are much more convenient to buy, though we did end up making a huge batch of titania since the shipping from Japan was being slow. And yeah, the coatings are applied LbL with what's basically an expensive fancy spinning version of a slide stainer. I can't back it up with tons of evidence yet, but the spinning action seems to make it much easier to get a nice even coating.
