A thin film with a refractive index close to that of air could be used to make photonic devices more efficient and mechanically stable. "By manipulating the structure of the aluminum oxide, which is dielectric, we've improved both its optical and mechanical properties," said North Carolina State University professor Chih-Hao Chang.

Harvard Spinoff to Commercialize Superresolution Microscopy Alternative
The techniques use complementary DNA strands to attach fluorescent dyes to the objects to be visualized. The time the DNA strands stay connected can be tuned based on their nucleotide sequences. This controls the fluorescence, which allows targets to be localized with higher precision than would be possible by other means.
