The glassy, amber-like polymer is ideal for long-term DNA storage, capable of preserving entire human genomes or digital files like photos., a team of MIT researchers has tried to replicate scientists’ recreating a colony of long-extinct dinosaurs using DNA that had been stored in amber for millions of years.
In contrast, the new method can store DNA at room temperature, safeguarding the molecules from damage caused by heat or moisture. According to researchers, DNA provides a very high-density method of storing this digital data: The world’s data might theoretically be stored in a coffee cup filled with DNA. DNA is also very stable and relatively easy to synthesize and sequence.In 2021, Banal and MIT professor Mark Bathe created a method to store DNA in silica particles, tagged to indicate their contents, leading to the spinout Cache DNA.
Overcoming styrene’s hydrophobicity, they identified three monomers to help dissolve and interact with DNA, forming spherical complexes. When heated, this solution turns into a glass-like block embedding DNA.
