When DNA is encapsulated in a silica sphere, the encoded information can be protected for storage and distribution, much in the way a bottle protects the message inside from the rough sea. As R. N. Grass et al. describe in their Communication on page 4269 ff., a silica layer only 10 nm thick is sufficient to protect DNA from high temperatures and aggressive radical conditions. The glass can be broken by reaction with HF and the information recovered for biochemical analysis.
