Japanese scientists have achieved an almost unbelievable breakthrough in data storage! So far they’ve accomplished the successful encoding and decoding of an 11-character computer password with a molecular alphabet. This illustration of an encoded password, “Dh&@dR%P0W¢,” shows how chemical data memory systems could be one way to securely save sensitive information. Tokens issued using this innovative method might be used to create tamper-proof collaborative solutions for product tracking or medical records and more.
To create these higher-functioning swapables, the research team, led by Eric Anslyn, used a molecular alphabet with 256 potential characters. One key aspect of this development is that it greatly broadens the range of data that could be stored on a molecular level. While speed is not the primary focus of this chemical data memory system, the ability to maintain long-term, tamper-proof storage is essential for its future use.
Advancements in the Encoding Process
Anslyn’s team optimized the protocol for encoding to streamline the process and increase efficiency. To get there, the team had to use a potentiostat—an instrument that typically retails for about US $10,000—to send carefully controlled electrical jolts to the molecules. This process initiated a chemical depurination reaction that enabled researchers to sequence the code much more efficiently.
The current approach still takes around 2.5 hours for degradation, sampling and electrochemical analysis. Researchers recognize the need to increase the speed of the readout to make it feasible for uses outside of an academic lab.
James Reuther remarked on the advancement by stating, “It’s a cool demonstration of how chemistry can be used in this space.” The implication is clear: there is much more potential to explore within this field of study.
Broad Applications and Future Prospects
The consequences of this research go beyond how password databases are stored. The technology holds promise for developing innovative and secure product labels that are hard to tamper with. It further protects medical records from unwarranted intrusion and disclosure. The researchers hope to make this kind of technology a part of everyday materials. This allows them the ability to design miniature data vaults to vastly improve security.
As Praveen Pasupathy noted, “There’s a path to interface it with more electronics, and that makes it more seamless for you to be able to connect it to computers.” Indeed, this partnership has the potential to bridge the gap between lab proof-of-concept, to field pilot, to ultimately commercialization.
Streamlined and Applicable Techniques
The electrochemical approach taken by Anslyn’s team has been described as “a lot more streamlined and broadly applicable” than traditional methods such as mass spectrometry. The researchers used ferrocenes that give off distinct signals at different voltages. This technique let them design unique signals for every stage of the encoding chain.
This quick and easy process unlocks a wide range of applications that need secure, convenient data storage solutions. Scientists are always working to improve their methodology and increase throughput. Because of that, it’s easier to imagine incorporating this technology into everyday objects.
