New DNA Storage Method Inspired By Jurassic Park

DNA is at the very heart of genetics and is the center of research and experimentation. Not all DNA can be used and analyzed right away and therefore must be stored. Researchers may simply want to store DNA so it can be used again in the future or even store it for preservation. DNA degrades over time, but that level of chemical degradation depends on various factors like type of DNA, temperature of storage, intended use, and length of time. In the most common form of storage in liquid nitrogen, DNA can last for decades. This method costs a lot for the constant need for cooling and energy consumption and upkeep of the researchers. Constant thawing and freezing can sometimes affect the life cycle of DNA but if it is kept at a relatively low temp it is no problem.

A solution for DNA storage recently came about after researchers developed a new form of storage inspired by the movie “Jurassic Park.” The researchers developed a glassy, amber-like polymer which is intended to be used in the long term storage of DNA, such as entire genomes or digital files like pictures. Unlike traditional methods of storing DNA, like using ultra-low temperatures, these polymers do not require freezing temperatures which require a large amount of energy consumption and are difficult to have in all parts of the world. The polymers can be stored at room temperature and still provide the same longevity and enhanced protection compared to its liquid nitrogen counterpart. The researchers have proven the ability to store an entire human genome, the Jurassic Park theme song encoded in DNA, and its ability to withstand 75 degrees Celsius. They are nearly complete in their process of making the polymer storage mainstream but need a method of streamlining the process of making capsules for the storage. 

This is groundbreaking because the DNA storage method has consistently been in the use of expensive liquid nitrogen storage. As mentioned above, that storage is expensive, difficult to maintain and not possible all over the world, and also requires a careful process to ensure optimum temperatures at all times. The new process could be great in the research field and especially in places where traditional storage methods are difficult to implement and maintain. The amount of research worldwide could skyrocket if more laboratories have access to efficient storage.
