Rutile replicas of butterfly scales: Rutile titania-based structures, retaining the morphology of wing scales of a Morpho butterfly (see pictures), are synthesized using an automated, surface sol–gel process. By doping a titanium alkoxide precursor solution with a tin alkoxide, rutile structures were formed at 450 °C. This method may be used to apply rutile coatings on other organic templates for biomedical, filtration, or optical applications.
